I like DNZ. Like Stick mentioned you're stuck with the ring spacing that could benefit from being a bit wider...but to date, I've not had a problem from them either with rings cracking or scopes failing from levered out ends. I'm running them on two Montana's and a herd of other rifles.
I've yet to try their 2 piece mounts (Hunt Master), but they would allow you to reverse the ends like Talley's for wider spacing...and leave a bit more room in the middle sans the connection bar. I need to pick up a pair and put them on a high mileage rifle to see how they fair.
