VCA is more flexible and does pumping fx with ease, + now comes with sidechain as standard (mine was early model that had this as upgrade), & the EQ is very useful. With behavior can also get a little grungy, but in general is cleaner than the FET. Probably the first option i would go with in your situ.

FET is hairy wooly ‘vibe’, and harder to manage levels post compression. Does pleasant things to digital synths for presence, and was good at its job when Machindedrum fed, though more for character than pumping imo. No sidechain kick option fyi.

Love the blend functions on both for over-compressing and mixing with clean signal.
