UAD Ampex 102 vs. Cranesong Phoenix

If you use UAD Ampex 102 on your mixbus do you really need Cranesong Phoenix on the mixbus too?

On my old PTHD8 I used Phoenix on the mixbus and loved it

but I’ve got a MBOX STUDIO setup now and use the UAD Ampex 102 on the mix bus and was thinking about getting the Phoenix beta but started to think if I really need it now.

Any thoughts or experience with this?
