Never had an issue with it, and it can't have a vent issue because the vent is behind it. It's also the same I.D. as PVC or ABS. In my experience it's a much more flexible and serviceable system than using glued pipe. Correctly installed it should be trouble free for decades.buy some pipe and the fittings you need, glue them together with a hub p trap. I am done using that cheap shit with the compression fittings that never quite works out with proper slope/angles/etc. doing it with real pipe you can make it so that it takes up less space and will never leak or have a vent issue.

Use whatever floats you boat. I've always operated on the premise that anything outside the wall should be easily serviceable.
