I don’t have a lot of experience with mounts since I’ve only owned two Losmandys so, I have no idea what a great adjustment system looks like or how they work ;). However, on both my mounts the Alt knob is quite good with no perceivable backlash. The AZ does have perceivable backlash but it’s easy to work around it. The idea is to work from just one side so, if you are east of the pole and need to move west, move the knob a little in that direction and, the closer you get to a good PA the less you turn the knob so that you don’t go past the pole. Presumably, if you happen to go past it, it will be by a negligible amount and you can leave it like that.

If you use digital means of PA the process is quite easy and quick. If you do a drift alignment it can take quite a while because of the necessary small movements needed to prevent switching direction, and the slow nature of the procedure to begin with

My 1.5 cents (not enough info to make up the entire 2 cents lol)
