I have used both UAD and Waves, my personal taste is the UAD sounds much better. It sounds good enough to use just to color track or master and tighten bass. Waves makes great stuff though and if I hadn’t used right next to the UAD I would have loved it. Same with 1176 for me…I have been debating ditching my Motu 8pre and Steinberg MR816csx along with the UAD 2 PCIe for the Apollo, but that’s another thread lol
