Best ring set after unlimited?

Are Explorer's Critical Rings even considered anymore?

I used one for a very long time up until lightning god rings came out/ I got 9% critical rate on my claw.

They are pretty awesome, but not anyone can grab one. You would have had to have been around for the events to obtain them. More critical rate is always awesome. Minimum crit damage probably helps out a bit too.

If I didn't have the ability to reach 100% critical rate without one, I would more than likely have picked it over a lightning god ring. I'm not sure if that's the best option though, I just really wanted 100% critical rate lol
