Neither purchase is inherently better,, it comes down to what the individual user values. With Apple or Logitech you have some assurance of a level of quality and warranty. My experience with knockoffs is some are just fine and others junk. That's not to say I don't buy knockoffs, but am aware of the tradeoffs.
Part of the purchase decision is wading through the garbage. Not everyone wants to do that to save some money.
That's the beauty of having choices; everyone gets to decide what is best for them.
In this case, while five times sounds like a big savings, it's not that much money in terms of actual cost difference.
That is actually an interesting behavioral economics point. People will view saving say 60 Euros on a 75 Euro price a significant savings while the same 60 Euros on a 2000 Euro sale as much less; when it's the same amount of money n either case.
