I used two different types of grip-type primer tools for several years, then switched to the RCBS bench-mounted primer tool. It has a long lever arm that gives plenty of pressure for crush-fitting primers and doesn't wear out my forearm the way the grip type priming tools do. I have a Forester press but have never used the priming feature because I don't like the idea of inserting primers individually by hand, nor do I like the idea of working between the press handles to place the case in the priming head. Just seems like an inconvenient way to prime cases. If it works for you, why change? OTOH, if you're gonna change, take a look at the RCBS tool that mounts on your bench (or on a piece of wood that you clamp to your bench top). You load up a tube of primers, put the tube on the tool, then seat them. Good open architecture for placing/removing brass and you have a good feel for seating primers consistently.
