I used sketch around 2017-2018 and the performance was really bad. Much worse than Illustrator. At the time I was on a top of the line 5K iMac.
Currently on an M2 Pro MBP and Figma is more responsive than Affinity Design. The latest versions of Illustrator have had a bunch of GPU rendering issues that affect performance. In fact these issues were the reason I started using Figma.
