With the exception of the original Massive, Kontakt, Reaktor, and (the defunct) Pro-53, I feel like its really hard to get something I like out of their synths. I've bought several of the regular Komplete kits over the years (their black friday sales are always generous, even for upgrades) and as they get more stuff they feel more disappointing. Some of the version upgrades hit especially hard (in a bad way), like Battery 3 to Battery 4.
And they keep releasing new versions of things without fixing annoying quirks in the previous versions...
As much as I want to like them and their software integrations I find myself reaching for other companies' plugins... like Serum is a way better Massive X, Sytrus is a way better FM8, etc etc
