Is Galvin Green stuff really worth the price???

iv got a cross waterproof suit-£100 couple years ago in my pro shop, callaway suit, 50 quid, jacket at tk maxx and trousers in a sale at auchterlonies. both very good suiots IMO.
id be quite prepared to splash out on GG stuff if i thought it was worth the money but i cant see it keeping me any drier than the ones iv got.

when i tried it on i always found the jackets to be very loose round the neck and thought the water would just pour in there, anyone else noticed this??
