seems like a stability question? but so far i've installed (useful/stable/convenient authorisation) so you might infer that these "just work lol" (at least for what i do):
presonus studio one 2 & updated to 3, ableton live 9/max 6, 112db eq & reverb, audio damage plugs, big tick rhino, blaukraut charlatan, bluearp, cakewalk z3ta+2, celemony melodyne, ddmf plugs, gforce mtron pro & minimonsta, gvst plugs, kirnu cream, martinic plugs, nomad factory isp plugs , ni, only reaktor & monark so far, plug'n'mix plugs, sknote plugs, sonimus plugs, stillwell plugs, toneboosters plugs, u-he plugs...
still on the todo list: voxengo, psp, discodsp, ni kontakt/guitar rig, wavearts, dmg, camel, linplug, korg, izotope, xils...
what will be installed next....?
now i'm not saying none of these have bugs, though i'm not hitting them, but at the same time don't fall for the "all software has bugs" blah because, while true-ish, bugs are usually there because of commercial development pressures and decisions, not because bugs are inherent to all software
