I have used the Dillon bench swager, the RCBS press swager and the RCBS stand-alone swager that's not unlike the Dillon in function.
None of them are worth a darn. They are fine for swaging 100 pieces of surplus 30-06 brass for hunting loads or something. But none will work well for those of us who might want to process large quantities of 223, 308 or 9mm.
As I think I've mentioned, the only thing I've used that's practical--outside of a Dillon 1050--is the Hornady Lock N Load AP swager. It still means handling each case again but it is consistent and fairly quick. The other press mounted system I've tried is the Swage It for the Dillon 650. It seems good in theory but hasn't worked well for me in practice. My only real complaint with the Hornady conversion is that it isn't available for 9mm.
The Hornady conversion is pretty much what's kept me from buying a Lee APP although I have to say I'm pretty close to ordering one. I've had an APP in my shopping cart a time or two but just haven't completely convinced myself that I need it.
