I’ve gone back & forth. I used to hate soft handles, as they grab dust & debris, and they tend to be bulkier.
I have had CAB handles start to gas off & stink. I shellacked them, & they’re beaters, but it happens.
PB Swiss’s Multicraft is my favorite handle.
I also have some hard handed Bondhus Felo, & older Snap-On‘s. They are excellent & tough. The Felo & Wera style of TPU inserts is quite good, as well.
But after a couple years in the trades, I’ve fallen back in love with Klein’s Cushion-Grip. The simple, round handle and the soft grip makes repetitive use easier, and really speeds up the initial installation of a fastener. The European ergonomic handles just aren’t as fast, and are more limited in how you can use them.
But when I’m working on clean equipment or in a. clean room, ( I do hospital repair & maintenance,) then I prefer a hard handle, to reduce the risk of contamination.
