Hydraulic disk brakes vs hydraulic rim brakes I am considering buying a new bike and have two models in mind. One features hydraulic rim brakes from Magura and the other has hydraulic disk brakes. Despite searching on the Internet and asking bike repair stores, I haven't found much information about pros and cons of one type compared to the other.



The common points I am aware of:


very good braking power
relatively hard to service yourself, almost impossible while on the road


The differences I am aware of:


I guess that hydraulic rim brakes are more sensitive to rain/mud/etc. (although I am not even sure, given the huge amount of pressure applied)
It's easier to remove your wheel with Magura rim brakes (in case of puncture for instance).




Some more specific questions:


Does the braking feel similar with both kinds?
Ease of service?
Ease of finding spare parts in remote places?
Difference in braking power?




I'm looking for general differences but a bit of context might help: the bike will be used for commuting and randonneuring, so mostly on roads and sometimes on gravel paths.
Some arguments in both directions:


Avoid disc brakes on a bike with quick release (QR) rather than through axles.
On the front loosening of QR by brake action may be a safety concern.
At both ends it is often difficult to position wheels with QR reliably enough to ensure there is no disc rub.
A QR equipped bike might be more convenient with rim brakes.
Six-bolt rotor bolts need to be tightened with exactly the same torque. One needs a small torque wrench or key for that. Uneven torque may lead to slightly warped discs and disc rub.
It is much easier to keep the brake surfaces of disc rotors clean than those of rims.
Riding in the wet may cause brake noise with disc brakes as well. Rain rides on lose surfaces usually kick up enough dirt to the rear disc to cause constant rub and noise.
Disc brakes allow much nicer rims. In particular carbon rims.
Magura rim brakes require mounting posts like cantilever brakes. There are no levers for drop bars. This rules then out for most road bikes. However, SRAM offers hydraulic rim brakes. *This is not correct, see comment by @stijn.
Don't restrict yourself to Magura when considering disc brakes. That they offer the best rim brakes and the best hydraulic system for rim brakes does not necessarily translate to disc brakes. For example, heat stability of their brake fluid might be an issue for discs while it does not matter for rim brakes.
