There's been a few reviews around comparing the various LA2A emulations.
A couple are here:
https://www.youtube.com/watch?v=Bk0zCdDOcmE https://en.audiofanzine.com/compressor/universal-audio/teletronix-la-2a-classic-leveler-collection/editorial/reviews/the-next-generation.html There was one I read (sorry - couldn't find it, else I'd have added a link) that said between UAD, Waves & Cakewalk's CA2A, the UAD and Waves were pretty much on par (maybe UAD had a slight edge), with Cakewalk's CA2A following closely behind.
So basically they said all three were very close, that Cakewalk'2 CA2A was still very good, but also that the price difference between the CA2A and UAD/Waves didn't necessarily reflect the difference in quality.
In the end I guess it's down to taste.
Personally, the convenience of having the CA2A in the Pro Channel is a big plus for me.
