34mm rings - Leupold Mark 4 vs Leupold PRW2 rings, are the Mark 4's worth the cost?

[Clicker]

I'm leaning towards the Mark 4 rings since they're aluminum and I prefer the 1/2" nut they use to clamp the ring to the rail instead of the Torx screws on the PRW2 rings. Less concerns over corrosion with Aluminum is plus also.
What say you guys? Any other 34mm rings I should be considering?

I have used TPS rings with great success. They are high quality and I have checked the ring bores to be very precise.
