I think the quality depends on the durability of the bag and how much they stretch over time. There's such a huge difference in prices. I have the bubblebagdude all mesh set. They're highly rated but supposed to be trash. Only 2 runs so far with dry ice and they're still just like new. If I only do 2 runs a year they'll last for several years for like $50 or whatever. But if I get 10 runs total out of them that's 5 years, so I'm cool with that $50 every 5 years. I can only make hash here in the winter. I break more glass then that $50.
If I used them every other month or processed more for hash then I do, then the $300 set of bags from elsewhere, that last forever, would be my choice. Buy cheap 1st and if you use it enough to wear it out, buy better. That's a rule my grandfather told me that I still use to this day 
You also have more stickers than I have, a lot more. A fine thing - I don't really do the sticker thing either. Maybe it has something to do with all the clamps.
