I think nearly all the rings mentioned are pretty good and I have used many of them over time. Aluminum or not, talley lightweights are good and I didn't see them mentioned, but the DNZ ring set up has been pretty good for me as well.
For a weaver base ring.. the Burris signatures are nice, no scope markes and you can get pretty close to a zero without using the scope adjustments.
Personally getting them on straight, locktited where required, and set to proper torque is really the key to most ring/base systems.
