No gear is going to make you a better hunter, but it can make you more comfortable, aid in staying out longer, etc.
I am all for advances in lightweight gear and I'll gladly throw some cash at something I think is going to cut significant weight without a reduction in function. There's a happy medium though, have to consider the diminishing returns just for an incremental cut in weight. Also have to consider bulk (volume). In my opinion sticks/climbing methods are the prime example of that. The lightest stick design possible is going to be bulkier than a folding stick, but I like folding sticks because they pack more streamlined. I could cut more bulk and weight by going to other methods, but I don't like the function of those. So you have to weigh other factors too...
A well-balanced, compact pack is going to have a lower perceived weight than a lighter pack that isn't balanced properly.
I also recognize, which you alluded to, there are situations where you don't need to go lightweight. I'll never sell my 20 lb Summit Climber. That thing is comfortable as heck and I know it like the back of my hand. It's my fastest climbing method, dead silent, and most comfortable in extreme cold and wet weather. It's not comfortable for a 2 mile hike or busting brush, but walking a half mile down a logging road with it is a cakewalk. You don't need a driver from 75 yards out. Learn your gear and know when to pull the right club out of the bag.
