You'll get a huge range of opinions on this one.
Let me add my 2 cents:
A few months back I switched from a starter vise to a Regal. It rotates, but it's not "true" rotary on the shank-axis, if that's what you're looking for.
For me, it's perfect. Rock-solid grip, and allows me to tie a #22 dry and switch to a #2 streamer with no adjustment.
