im ID and watched them. safely say some of them are an untapped gem that is cucked by being Niji ID and not holo ID, while some are as an anon said "Generic mixed-gender tubers" so heres a quick review. on ones i watched
>Hana Macchia - On good days shes entertaining, her rare streams with papa macchia are amazing. Buffed by being american
>Taka Radjiman - Not the biggest fan of the proper businessman lingo larp but if you like those type of stuff go watch
>ZEA - I didnt watch her... rather boring generic
>Miyu Ottavia - An untapped gem, Great singer, fun personality, nerfed by being Niji ID. watch her please
>Rai - I didnt watch him, never found him too appealing
>Amicia Michella - Chill vibes all around, relaxing, great to watch while working. p good singer.
>Riksa Dhirendra - Honestly another untapped gem, great streamer for the indo market, funny, interacts with chat, can break into houses easily and has a fun series of teaching how to speak Sunda. Nerfed by being Niji ID so fellow Indogs please watch
>Azura - Didnt watch, but my friend did and he said shes cool.
>Nara Haramaung - not into ara ara and i didnt watch, tho her collab with hana was funny.
>Layla Alstroemeria - Not my favourite BUT she has a really nice voice, think of moona and ayunda mixed, so i would recommend
>Siska Leontyne - Watch her shes great, mostly chill but can be toxic in a funny way while playing dota and other multiplayer games, and has a super relaxing voice like kaela. Not the greatest singer but shes great, good to watch while working, Nerfed by being Niji ID
>Etna Crimson - Didn't watch, but from collabs she did with bobon and siska shes funny. if i remember it correctly shes kinda like kobo, though take it with a grain of salt
>Bonniview Pranaja - MOST BASED MAN ALIVE GOD DAMN and also funny. Watch him. NERFED by being Niji ID
>Derem Kado - I used to not like her cause its an obvious super duper forced loli (act cutesy in a bad way), BUT she has changed her avatar and is no longer a forced loli, and is just a regular gal, might give her another chance in the future
>Nagisa Arcinia - Didnt watch her but shes a better loli than old derem, comparable to himemori luna.
>Reza Avanluna - hes a walking talking Yaoi, if you like those stuff go ahead, im not a fan so i didnt watch him much apart from the collabs with hana.
>Mika Melatika - Shes a Niji EN member that collabs with the EN Male, not that bad, but horni. so if u like Niji EN watch her
>Hyona and Xia - i dont know who these are
TL:DR
Niji ID was a failure, other than hana, siska and mika it was a flop, but there are gems in it that are great and some that are underrated/overhated,
Final recommendations are
>Hana Macchia
>Siska Leontyne
>Miyu Ottavia
>Riksa Dhirendra
>Bonnivier Pranaja
The rest range from okay to not great.
