Perhaps this video will light a fire beneath the developers’ bottoms:
To be fair, though, in 2.81 I can perform the same operations using the new sculpt tools and butter smooth at that. And basic selections work a little slower on my aging system compared to Max in that video - not bad at all.
Just the raw edit mode performance needs a kick in the bottom. I am confident the devs will get there by 2.82 or 2.83/4. Matter of time. They seem to be aware of the bottlenecks.
PS I also tested the same model in Cinema4D 20 and Lightwave 2019 Modeler.
C4D does marginally better than Blender in raw performance, with selections slower, and transform operations about twice as fast as Blender in Edit mode. Sculpt mode in C4D was pointless and unusable: far too slow. Utterly unusable.
While Lightwave Modeler did keep up with basic selections, transforming large swathes of geometry was WAY slower than either Blender or C4D. But what can you expect from software which did not get any major updates in the past 15 years, or so.
