How good is the AMS 2 drying vs an independent drying unit?

So I have an independent drying thing for 1 spool. It works, but it only does 1 spool and I can't use the thing mix with the AMS. I'm assuming at some point the AMS 2 will be able to dry and print at the same time. Assuming it does, how good is it in the drying function compared to a normal unit that can only dry 1 thing at a time?

Note I don't print Nylon or PC. I might start printing ASA at some point, but I mostly print PLA, PETG, and sometimes TPU. From my understanding the AMS can only go up to 65, but IDK if that matters with someone like me
