I’m not sure its worth going down that road , but we’ll try.
I guess, if we’re allowed,we could say, post your rig, what kind of mesh you have , on the blender thread if there is one, and I"ll respond with my rig. I"d rather be editing, than not.
There is no ‘blender’ forum so we’re stuck doing it this way.
Many have this problem, and if it weren’t for that problem, a well known problem that app has, I"d be using a lot more.
Actually I ‘needed’ to use said app last night, but I can’t as using edit mode there, is beyond frustrating; not happening, unfortunately , and its the ‘only’ app I have , that atm I can ‘afford’, where I can do such things. That should tell you something. Hence my recommendation of Maya LT ( or Maya if he can afford it ) , all based on personal experience nothing more.
Given you brought it up, I feel I should offer something illustrating what I and others go through in Edit mode:
Page 2 last post by ace dragon, one of the dev’s I think or a longtime user/coder not sure:
" Work on rewriting the OpenGL code is already underway in the 2.8 branch (and a recent Sunday Meeting has the developer hinting at the code being ready for tests sometime soon).
All we can do is wait as of now, but please note that the developers are indeed aware of Blender’s OpenGL being archaic as shown by the project. "
So as you see, its not personal against app X, its true and its why I can’t recommend app X ( all cases would have to apply), hence Maya /LT which I"ve used and wish almost everyday I had ) ie: zero lag on millions of triangles ) 
Peace out
