The AMS has caused me some headaches. Filament can and will break off inside the AMS or in the hub on the back. If it is a big piece, its usually easy to find and clear, but I had a small piece that was less than an inch long bust off from slot 3 (which I had not used in weeks) and fall down into the 4:1 on the bottom of the AMS. I took it apart at least 3 times before I found it.
As for waste, it can waste a lot depending on how many changes you make. A neat trick is to set it up to purge into an object like a fidget toy. Makes it look cool with the different colors and helps prevent bleeding colors into your main print.
Working on the P1S is not going to be as easy as the A1 but luckily I havent had to do anything other than find chunks of broken filament. If you know you'll only be printing PLA, the A1 would probably be my choice but I did not want to limit myself. I print with PLA, PETG, and ASA. I will eventually start printing reinforced materials as well. I bought the hardened extruder gears but do not have the hardened nozzles yet.
