Some of the maxcady replicas are better than others, but many of them fall far short of the authentic vintage pieces. I own at least one of every fight club replica maxcady has produced and I also own their true vintage counterparts. So I can compare them side by side and I'm not just talking about fabrics, the colors, details, fit etc. are all different. For example, the sock it to me they made is one of my least favorite replicas and doesn't hold a candle to the original. The moto and maple leaves aren't bad, but they are the wrong colors and materials. They just have a 'costume' feel to them. Same goes for the toucan, but I haven't come across a true vintage alternative for that one yet. On the other hand, the track pants are great and I really like the leaf hoodie.
There will always be a market for true vintage pieces as long as there are the collectors that appreciate them. I have pieces that I will never sell, because they are truly one-of-a-kind items with a 30, 40, or even 50+ year history behind them. But I like the replicas too and i appreciate them for different reasons.
