I have 65 UAD plugins I have bought always on special.. I have the QUAD UAD2 Card and a Silverface Quad Apollo with TB3 upgrade. I won't (he says now) be buying anything more off them. I simply don't use them all.. BUT, what I do use and it varies on application, sounds, and behaves beautifully. I get the most mileage when recording mics and playing my guitar or bass into the unison preamps. Stuff like the Capital Records chamber.. are just.. well, incredible!.
