I've decided to try this, answering these questions.

1 - Who stays up late at night to read and who sleeps with their head on their lap?

Steve stays awake reading and Bucky likes to sleep with his head on his lap.

2 - Who has the most complicated Starbucks order?

Bucky has the complicated order - usually lots of whipped cream - and Steve prefers it simple.

3 - Who wants kids and how many?

Steve would really want kids, and probably one or two would be enough. Gender doesn't matter, in that case.

4 - Who looks best in a tux?

Both of them can rock a tuxedo, but Bucky looks slightly better in one.

5 - Who despises the other's favourite food?

Bucky despises Steve's favourite food, which, surprisingly, is what they always had enough of back in the Forties.

6 - Who is the dog person and who is the cat person?

Steve adores dogs, he wants a pitbull, specifically. Bucky loves cats, always had since the past.

7 - Who feeds the ducks at the park?

Bucky is pretty much an all around animal lover, not only cats. He feeds the ducks whenever they walk through the park.

8 - Who cries over the ASPCA commercials?

Both of them, but it's Steve who has to physically restrain Bucky from going out to buy all of the homeless animals in the area.

9 - Who has the motherly instincts?

It had always been Bucky looking out for Steve, and he didn't see any reason to change that.

10 - Who laughs too much?

Steve has a loud, long laugh. When he laughs, he really gets into it, pretty much throwing his whole body into it.

11 - Who is the worst cook?

Steve isn't too great at cooking in general. He never really has been, besides stews and soups. Bucky is the better chef.

12 - Who watches too much tv?

It's a mix between the two. Bucky loves watching Supernatural, specifically, ever since Bruce got him into it. Yes, they ship Destiel. However, Steve and Bucky often have Disney marathons.

So what'd you think? Should I do a few more of these? I figured I would change it up a little.
