The newer Coax still has the issue with some big cartridges that it was not designed to handle, I have one of those, won't handle the rim on my 450-400NE. It isn't the only tool on the bench with that issue. But, that is ok, I still have the Rockchucker to do that with. Haven't bothered changing jaws out yet to do a small cartridge, seeing as I have the other press and I am not shooting smallbore matches.
Lots of times I will use a Lee handpress for those anyway.
If I didn't already have any other press, in the long term, the Coax is the best of the bunch, I'd buy it first if I had it to do all over again. No Lock n Load bushings needed, no shellholders, Hornady lockrings work, no special dies or adaptors needed, and old RCBS ones work as well. It is comfortable to work with. And it works as advertised.
