I love NND despite the majority of westerners saying they hate it. It's my #1 place to go for Vocaloid originals and UTAU things alike!! Plus like you said, there are a lot of hidden gem producers who are on NND only . It recently got a UI update which I found really refreshing and easier to navigate around which I feel was one of the biggest complaints from people (but tbh i never minded the old one either).
