Is 100% Remy human hair good?

I'm considering purchasing a wig made from 100% Remy human hair, but I'm not entirely sure if it's a good choice. Could you please elaborate on the qualities of 100% Remy human hair? Is it durable? Does it blend well with natural hair? How does it hold up to styling? And most importantly, is it worth the investment? I'm hoping to get a wig that looks natural and lasts for a long time, so I'd really appreciate your insights on this matter.
