Yeah, this is a question best answered based on where you foresee spending the majority of your time. For me, hunting mainly the Colorado high country, some trips up to Wyoming and to Montana, I am looking for outer shell, not just rain gear. I want something that serves multiple duties. An outer shell to cut the wind when sitting for hours and glassing. An outer layer to put on as a last resort with all my other layers, when the temps drop. An outer layer that is waterproof and serves as rain gear when I am caught in an afternoon storm.
For me, I'm not necessarily looking for pack ability, but rather comfort, quiet, etc. ultra light package rain gear doesn't fit my style or areas I hunt.
You need to analyze the type of area, and type of hunting you'll be doing.
