Road bikes rim brake or disc brake I am about to buy a new Road bike and there seems to be a host new road bikes with disc brakes, I've had a Mountain bike with disc and it's fine, just wondering what the pros and cons of having a road bike with discs apart from the looks, should I stick with the traditional proven rim brake or have a more in depth look at disc brakes as the industry seems to be inclining towards discs.. I will not be changing bikes for at least 3 years so want to make the right decision.

Any experiences from roadies who have used disc brakes would be welcome as well as your opinions. 

Many Thanks

I have a road/gravel bike with a disk front brake and there are almost no downsides for solo riding from my experience. 

Pros:


Much more flexibility is choosing wheel size and tire. I can run fat tire 650b wheels or skinny 700c wheels. 
Much better braking in wet conditions, braking in dry conditions is similar, but with better control (i.e. modulation). 
Easier to get wheels off when you have a flat. 
Most are either self-adjusting for pad wear or have a simple finger adjustment.


Cons:


Slightly heavier wheels and brakes. 
Rotors get hot, brake fade is a possibility if you consistently drag the brake. Long steep descents take some "brake heat" management. This can also be an issue with rim brakes, but generally it takes a much longer descent and more abuse to cause problems with rim brakes. 
Hydro brakes have more mechanical complexity, difficult to impossible to make on the road repairs.
I use wire disk brakes on my road bike with no issues. 
Putting the wheel back on is a bit more fiddly. 
If you ride in a group often, there are some safety issues around hot rotors and potential crashes.
