I’m pretty brutal on my machines, and if my 8 gig m1 really only starts to beach ball when multiple accounts are open, and those accounts all have bloated multimedia software running.
My 16 gig machines can handle that use case fine, but the 8 gig machine will occasionally beach ball.
Personally, I won’t buy an 8 gig config again. But I’m a fucking monster that leaves a million bloated things open across multiple active user sessions.
