I don't mountain bike anymore, I don't ride in the snow, and I won't start a ride if it's raining. As such, I don't have anything against disc brakes but I'm not all "gaga" over them either. If you tend to remove your front wheel when carrying your bike in your car, mechanical disc brakes are a little quicker and easier. Hydraulic discs are also easier so long as you avoid accidentally pressing the brake lever with no disc in the caliper. If I were buying a new bike for myself today the brake style would be a non-factor. Whatever came on the bike I liked best otherwise would be fine with me.
Then again, I'm a retro grouch and a non-repentant one at that.
