AvenueX on YT had a pretty good comparison and review for both. TL;DW the Netflix one fails to use its budget for anything, and instead tries to appeal to its audience (or at least who Netflix thinks is their audience) with sex scenes, romance and dumbed down concepts. She also comments a bit about how Netflix politically charged it (which is an unfortunate thing to hapoen to Three-Body). I was personally a great enjoyer of the TC 三体 since I liked the calmer pacing (I feel it is mostly the western audience who have a problem with it).
