So I am attempting some games that are not things I might normally play, and the Fallout series has some aspects I think I might like and some I think I might not at all like. I have the option between Fallout 3 and New Vegas. So I know people here seem to like New Vegas more but I'll just list a few things and hopefully you guys could tell me which would fit me better? Thank you!

So which of the two games fits better in to these:
-Lots of customization
-Lots of different dialogue choices
-More open
-Less drab environment
-Interesting characters
-Easier
-Less fighting (something I am very much dreading is the fighting)
