Hi Iliya, as Amy says, most of us or on FB so you'll get more replies there. However my tuppence worth - i have road bikes with standard rim brakes, a station bike with V-brakes and a mountain bike with discs.
Discs will stop you quicker, no question, and are less affected by rain, mud etc so ideal for the sort of mountain biking where you need to stop or slow down on a steep muddy trail.
On the road less so. There are few occasions where you really need to slam on the brakes - look ahead as you would in a car and anticipate hazards. This is especially important when commuting and surrounded by muppets in cars, buses etc who aren't paying attention. The odd time someone has grabbed a fistful of rim brakes on the CR, we've had a pile up; discs which are way more powerful will only make that worse. Discs also tend to make you take more risks - coming down a steep wet road on my mountain bike I will go faster than on my road bike and brake later.
I have descended Tourmalet, Bwlch in Wales and our steeper Surrey Hills on rim brakes, often in the wet. Brake earlier and adjust your speed to the conditions. Same laws of physics apply on a bike as in a car - be able to stop in the distance you can see to be clear ON YOUR SIDE OF THE ROAD, and if the vanishing point of the bend is getting closer, you're going too fast.
Finally, as Amy says, rim brakes are easier to maintain and fix by the side of the road if you ever need to.
