Firstly, if you run out of 4 stash tabs during the story you're picking up way too much. Easy mistake to make, but POE drops way too much loot and most of it is useless. If you're attempting to sell what you've found in the story you're also just wasting space.
Supporter packs aren't there for value, they are there as a "supporter pack". You buy it to give money to the dev, and you get some cosmetics, as well as most of the price of the pack as premium currency, which you can spend on more cosmetics, or stash tabs. I'd argue that character MTX isn't even worth spending money on given the amount of flashy skills and effects there are, that obscure your character, but that's a different argument.
If you're happy to pay $60 up-front for the game, why not just buy the stash tabs and be happy? $60 buys you more than you'll ever fill up.
As someone who played for ~3 years before dropping a dime on the game, I have to say I don't see the "quirks" other than stash space. The only other incentive is the regular "spend points to get a free box" where everyone just spends the equivalent of $0.50 on a bug to get theirs, using up the leftover points they had.
