UAD is generally better dynamics/ eq/ verb plug ins... so us'em for the most important sounds, powercore synths, x3 (hope u get x5 soon) and processing on slightly less important sounds...
UAD is the cherry on top powercore is the workhorse the "brute force"... but don't get me wrong it is very good and sounds excellent!
Just wish fruity had a better mixer and Delay compensation for plug ins like such!
