I had all the OGs from V-XIV, and early retros (I-III '94) abut I balled in all of them. Quite frankly when I see people talking about the quality of the OG's, I have to laugh. Some of the OGs, especially in the later years, were garbage quality. I can't tell you how many pairs I had early toe separation on, horrible creasing, easy scuffing. Particularly 10's, 12's, and 14's (the foam midsoles were utter garbage).
Now I only wear the retros as regular kicks, not basketball shoes, and I haven't found any issue with the quality. In a few cases they've obviously switched materials altogether from the OG colorways, and I'm not in support of that. But as far as the materials go on many of the recent pickups I've made, I don't have complaints. Maybe I don't wear them enough to see many of the issues I had with the OGs when I played basketball in them, but most of them have held up pretty well after many wears.
I always thought Jordan had great designs, but quality wise the OGs were horribly hit or miss. Just like anything people want to remember it how they choose (which is usually fondly), especially in comparison to newer versions of the same product. Nothing is changing back time, but overall I think the OG vs Retro quality issue is way overblown. The best is when I see 17-19 year olds talking about the quality of retros being poor. These kids weren't even wearing Jordans until after the production had gone from Nike to JB (which I suppose is still just slicing the same thing a different way). I'm sure I'll be in the minority here, but that's just my feelings on things. The reality is probably that just about every major brand (Nike, Adidas, and Reebok) have cut quality in favor of cost reductions, especially on retro shoes.
