Apple silicon M1 and After Effects - The All-In-One Thread

Hello community!

I'm starting this thread in hope to see opinions and experiences with the combo mentioned in the subject line. I've been scrolling through the threads here and a big picture is forming and it can be distilled into 2 words: slow & unstable.

But would you argue the opposite? My situation is that my 2017 27-inch Mac is starting to feel slow for my needs and I'm flirting with the Mac Studio option but the leap forward seems rushed and troublesome. I'll start with my biggest questions:

1. So is AE working properly with M1? Really?

2. What about plugins/extensions? Do old Intel-era plugins work with Apple Silicon Macs and Apple Silicon AE? I'm pretty sure not all the paid and free plugins will ever be updated.

3. Combining 1 & 2: Would the M1 Mac be more trouble than an improvement? Should I just wait for some vague moment in time when everything is better and these questions are obsolete?

4. Same questions actually about PS and ME.
