I have powergrips and I love them. I can get in and out of them very easily, and they feel much more secure than my previous cages/straps (two different sets, one set being Shimano 105). I feel they are much more comfortable on my feet, and resistance is never a problem with them. I have had them about a year and I have not noticed any significant wear. Sure, clips/straps make your bike look more pretty or "tarck", but I prefer function over fashion, especially when it comes to something as important as foot retention.
