If there was no such thing as rain, for instance living in SE Spain where rain is so rare it's basically a desert, I'd go rim brakes.
Or if you only ever go out in the dry and wouldn't even dare to go out if rain was even a possibility, rim brakes again.
Problem in the UK is that you can head out in fine weather and still get caught out, I hate the sound of my expensive rims being machined away in wet weather.
If you ride pretty much every day and live in the UK, you will see rain, so that's why all my bikes apart from one are now disc. The one with rim brakes is the one i take to the alps every year (not this year
).
