I like the ESP Cryogen range, haven't even considered looking at other hooks for a couple of seasons now... A lot is down to personal choice. Not used the barbless though.....
Gardener Mugga's are highly thought of and I'd happily use them without flinching if my favoured hooks were out of stock.....
Not much help really, but I try to stick to what I've all ready got confidence in..... Chopping and changing can be a long , dark, winding road...... Headaches and half used packets of this and that.
If I was really in a dilemma over the two, I'd buy a packet of each and make a comparison, choose one, and stick with it.... Job done.
