Not sure how better it is actually, but in the past they had load of problem with the so-called GDI (++) alike implementation, so the screen refresh was not slow.... bbbbbbbbbbbbbbbbbbbuuuuuuuuuuuuuuuuuuuuuuutttttttt tttttttttttttt rrrrrrrrrrrrrrrrrreeeeeeeeeeeeeaaaaaaaaaaaaaaaalll lllllllllllllllllllyyyyyyyyyyyyyyy slow. The interface by itself, it take ages to load, their AutoHide&Pin implementation is a pain to work with.

Everything you want to add into is a plug-in... once again this increase the load time again and again. Sure it is a really powerfull IDE, but it is bloat coded and have serious memory leak on various plug-in.

Probably because it is an open source, so everyone can access/modify it, with good or bad programming skills.

I understand why Microchip haven't use it...
