I would opt for the RCBS Rock Chucker; simply because the one on my reloading bench has worked well for me over many hundreds of thousands of Pistol and Rifle since 1975. (1hole, Sorry about upstaging your 35 years with my 45 year machine - I am sure someone on the site will report an even longer use of a Rock Chucker).
For my 50BMG I use a dedicated Lee Classic Cast 50 BMG Single Stage Press Kit.
For swaging I use a Corbin CSP-1 S press (since 1989 or so). Also use this for reloading pistol and rifle ammo when I have the Rock Chucker set up with BT Snipers Auto Eject apparatus and 5/16 Copper Tubing Jacket maker dies and do not want to take it apart.
