Yep, personal preference. Hopefully we won't be needing a "Only Pump Vs-thread Allowed".
Seriously, though, it's going to depend on what you like, and what's comfortable for you. A lot of guys really like the Phantom/Carter/Lapco style Nelson guns... which I can't shoot worth a darn. Some really like the Sniper/Chipley guns. There's also custom brass from Palmer.
It's a good time to be looking at pumps.
