I've had the same experience and tend to just buy the fake Rapha ones, as the quality tends to be pretty good and they're fairly subtle. I've had good experiences with this store https://m.aliexpress.com/item/32824323253.html
Sorry just seen this. I haven't compared side by side tbh but they feel like 'cycling socks' i.e. different thicknesses in different places, tight fitting, long. I'd be happier if they were plain white, but I'm about to order a few new pairs for summer.
