I choose guitar. With a guitar, you can actually create a tune. You can do that with the keyboard too, but those are for peeps who were forced to take classes in school and didn't have guitar as an option.
As far as drums.....those are for peeps who can keep a beat. That's actually harder than you might think, but you will NEVER create a tune just by playing the drums.....oh wait, there's that lame rap music garbage now, so I guess you CAN create (what they call) music just by making loud thumping drum beats.....whatever....they CALL that music, but I don't.
Bass is just for peeps that can't play a real guitar well enough, but would like to, so they play bass.
Only people like Trans-Siberian Orchestra can make the "other" stuff work....at least as far as I'm concerned anyway.
Yeah, that's my assessment of the whole situation. Bite me if you don't like it.Â
 The truth hurts, don't it?
