I like the Conetrol and S&K style rings/bases. Both are sleek, solid and windage adjustable. I've used them on small caliber rifles up to 340 Weatherby and they've worked perfectly for me. Burris Signature Zee Rings are stout also and perhaps a bit cheaper. Depending on the rifle you might use "Redfield" type bases & rings from a number of manufacturers, but they would be far and away my last choice. I've had more than one "Redfield" type come apart for a variety of reasons--some were my fault, others were due to the inherently weak design.
