Between the feeder and the stand, they're often pretty heavy, so probably best to commit it to a given tool.
I have the little micro Comatic on my router table, its pretty good for that purpose but it's under-structured for heavier work and it wont run parts faster than the lowest speed setting but otherwise a neat thing to have for that machine.
I've run this little feeder on the tablesaw occasionally but it's such a PITA to swap them back and forth. That said, I'd go heavy enough that you can mount the support pretty far away from the fence so that it has a pretty broad range.
I put the mid sized Comatic bandsaw feeder on the bandsaw, it's great for everything except large resawing. And FYI, most bandsaw fences are not designed for putting the amount of pressure a feeder applies. I had to beef up the pin and bolt that retain my fence to square. The original design would push out of square fairly easily, so I ended up boring out the mount, installing a 16mm shoulder bolt with a 24mm shoulder diameter and replacing the 8mm roll pin with a 13mm solid steel pin. If it breaks again I'll replace it with the proper roller fence. This feeder runs too fast for resawing, even at the slowest speed, even on a 5hp bandsaw with a 1.3TPI carbide blade.
On the restored Martin I have an old Festo feeder that I restored, that thing is amazing. 8 speeds and built like an absolute tank. I replaced the wheels with some new fancy ones from Western Roller and it is smooth as can be. Absolute pleasure to run.
Bumbling forward into the unknown.
