I'm writing a book, most of it is just thoughts right now. I'd like to just talk things over.

Idk what style to write in...1st or 3rd. To me, it seems like 3rd would be easier, but it would get more boring. 1st seems fun, but hard to write.

(of coarse i would make it more interesting than this)

Jack drug himself over to the fridge, feeling the lingering effects of his hang over. The world was spinning a she fumbled for the door, struggling to slide it open. What would help with this hang over?

Or...

I felt dizzy, the world was spinning as a strong nausea washed over me. I wanted to puke until I had nothing left inside my stomach. A bletch rumbled up through my chest. Was that pizza? When the heck did I have pizza? My hands fumbled, struggling to grab onto the moving fridge handle.

...it's really up to you. (This is the worst answer in history :P) Imo, 1st person has a lot of problems. For instance, why do lots of characters in 1st POV whine about everything all the time, or seem to think the world is against them? Another potential problem is lack of characterization. The character has zero personality and basically is a fill-in for the readers. (Think Bella Swan from Twilight--there's nothing remotely interesting about her.) I've read novels where 1st POV works really well (The Curious Incident of the Dog in the Night-time), but also novels where it is a disaster (lots of YA--no offense). Same goes for 3rd POV.

Think about how you want the reader(s) to interact with your character. 1st person can be very personal (which is a good and bad thing), while 3rd person seems a little more detached, but at the same time 3rd POV works well in the bigger scope of the story, because the reader sees more. Whereas 1st POV is objective (you only see what the MC is seeing) and can be claustrophobic. Both POVs can be great--it all depends on how you work with it.

nods See i'd go with 3rd person, but i'm doing a story not focusing on humans. I feel that 3rd person would make that difficult for the reader to get attached to the main character.

If that is what you think, then go with 1st person :) So the story is from a non-human character's POV (a cat or alien)? In this case I think 1st person would definitely make for an interesting narrative. (Of course, you can always try writing out a small scene using both 1st and 3rd person, and then compare the two and see which one works. But I'd just go with your gut feeling--it's usually right.)

both styles can be interesting, - and quite a lot of the time, I doubt readers often notice

1st is nice as it can give a more direct insight into what that person is thinking, and as you said, with a nonhuman character, may even better allow readers to identify and get attached to your main character

however, I like 3rd in that it is far easier to switch perspective, to not tie yourself down to the one character often many things happen in a story that that one character may not notice, but you want your readers to know about (however, it can be equally as interesting being restricted to only knowing what one character knows, and therefore hopefully being as surprised as they are)

you could always try writing a bit of both, just to see which comes more naturally ^_^

It's really a matter of how deep you want to go with your characters. When something is 1st person, it's easier for the reader to get a feel for what's going on inside the main character's head, and you could probably dig into it better. In my opinion, 3rd person is more "distant", it is not truly known what's going on in everyone's mind. It's probably better to do 3rd person when there are more characters. I don't know, that's just my take on it. I used to prefer 3rd person but I am now writing almost all my works in 1st.

I finished two short stories for my pets here on Subeta. One is in 3rd and the other one in 1st. I like 1st more. I like to feel the character at the moment. Imagining the whole world of the story around me. The only thing I seriously hate is that i really need to think hard not start every sentence with I want.. I placed... I love I can't realy keep concentrated on 3rd. There's a book on my nightstand that interests me so badly but i hate to read it because it's in 3rd. But i guess every person feels different about that :D

There are pluses and minuses to every POV. Of the two, people generally knock first person for a variety of untrue reasons.One of my favorite first person novels is The Great Gatsby. If you're thinking about writing in first (or third), you should read up on how writers use the various POV to convey a story.

My advice to you would be to write what's most comfortable for you. Writers can do a rotten job in first person and in third.

As everyone else has said, both points of view have their flaws and, no matter which one you choose, you'll have people who won't enjoy the story simply because of your choice. I find that, as said, first person tends to revolve around a character that can lack personality. The point of first person is to draw the reader into the story and, if the reader doesn't relate with the character at all, then that can cause some problems, leading to a bland protagonist. Personally, I prefer omniscient third person, because you don't receive a biased opinion of what is happening in the story. The narrative takes into consideration other characters, environment (such as weather and setting without making long, drawn out descriptions that often turn poetic and, in some instances, ruin the tone of the character), time frame, etc.
