I liked priorities. I didn't make much use of them, of course, but I did start whole-system compilation with a lower priority so it wouldn't interfere with me playing a CPU-intensive game. It didn't make a big difference, but it was nice. If I didn't want to play that game the low-priority processes could still get all the CPU time, which wouldn't be the case if there was a fixed limit on the time they could get.
I didn 't see any particular increase or decrease in subjective quality when Linux went tickless. For my usage, (web, game, compiling,) it was fine both ways. I don't think I tested it as carefully as I did faster ticks and preemptable kernel.
