I don't have experience but have heard from many that it is easy to over inflate with cartridges. The convenience does not outweigh the danger of not having a cartridge when you need one. A mini pump won't do that. Have you considered solid, flat free tires? A little extra weight and expense but an option.

I do not know. I have never ridden on any.
A good bike shop would let you ride a bike kitted out with them for a test. I'm sure that there are articles about it out there.
