Personally, I cannot stand electronic muffs. Which is largely irrelevant, since I haven't worn muffs for about 8 years now. I don't know what happened, but somewhere in my mid 30s, they suddenly started getting in the way. Even with low profile muffs, I can't get a proper cheek weld on a long arm and hot have the right muff get knocked off of my ear every shot.
It's all foamies for me. It's easy to get more than 30dB protection, and they're cheap cheap cheap!
That being said, for the 20-something years I did wear ear muffs, I was partial to Peltor. They've got a wide variety of styles, most of them 30 dB protection, and all in the $20 range.
