Which instrument should I learn, bass or drums?

How on earth did you expect to become adequate on drums, much less proficient enough to do rhythm for a band, during only one year of learning?

Bass. Definitely bass. You'll still suck but I can't imagine they'll expect any difficult lines from you.

I am a good musician, and I pick things up very quickly. I'm aware that I won't be fantastic, but I should be able to get up to an adequate standard.

I retract my suggestion. That level of self-assurance demands a drummer.

If by better musician you mean well rounded having knowledge of percussion then I can't argue there. If you aren't concerned with hearing loss and would rather play drums, I don't see why not. Everyone's always looking for a drummer, and at least where I'm from there hardly are any. Nobody cares about bass players, it's always ends up as the third guitarist in the group that wasn't good enough for rhythm guitar.

Everyone always needs a drummer, and you could learn to at least keep a beat in a year. Go for it.

Bass, if only for the fact that it will be easier to practice. Drums require a dedicated space and tolerant neighbors. If that's not an issue for you, and you have the co-ordination and the funds, then go for drums, but I would say it'll be easier to get good on a bass in a year because you'll be able to practice more often, and a bass is much more portable than a drumset.
