Especially in Taipei, they hit a price and convenience point where taking an Uber is essentially doing a task on my phone in exchange for having to wait longer to get a ride. To be clear, it usually takes about 15 to 90 seconds of waiting to get a cab.
Outside of Taipei, any convenience store (which are basically all over the place) will call a cab for you and again, it's still a pretty short wait unless you're in a remote area in the mountains or something.

Clean, cheap usually friendly drivers with lots of local insight and you're guaranteed not to be cheated.
