Otto Noizebarrier vs Peltor TEP-100: anyone with 1st hand experience?

So I am looking at buying either the Otto Noizebarrier or the Peltor TEP-100 electronic ear plugs, and I wanted to see if anyone here had experience with both brands and could tell me which one you prefer. I did a search and found people here who praised both, but no one compared the two against each other. I will be using these at the range and for hunting. I previously used the Walker earplugs, but I don't like having to use hearing aid batteries.

Thank you for your time and input.
