I play the drums, started out when I was 16 or so and I took to it quite easily. I've been playing guitar since I was 14 or so, but I was never very serious about it. After I got 20-something, I stepped up a bit on the seriousness and started playing guitar in one of the bands I'm in (before, I only played drums in bands) and now I actually like it more than drums. Now I'll say I'm somewhat competent with both.
It's true, playing guitar is much easier frmo a logistics point of view. I can turn the sound off the TV and play on it during the commercial breaks and it's so much easier to bring over to your friend's house for a little rehearsal and lyrics writing.
