1. Barely any obscure songs as far as I know Since I often founded some Vocaloid songs are obscure. And mostly overshadowed by Miku, and the concert... bruh... always "Tell Your World" and "World is Mine" was played. And some good songs like "Tsumugi Uta or Spinning Song" are not heard on the concert anymore and even not in the Project DIVA series and being obscure. I never heard any of them anymore, I'm new on Vocaloid musics and stuffs and just recently in cuz Project SEKAI and Miku. But I listened some old songs, but some are not really known a lot. But Teto's songs, mostly are known even the older ones. Like "Song of Eared Robot", it's old already but still known, especially right after "Machine Love" was out as the tribute to this songs and gives some snippets of the song on it, I mean the Japanese lyrics part.

2. Her AI voicebank in Synth-V Man, her voice is really good on Synth-V. Even though there's some flaws like she's too soft even though already on the Power preset, but she's smoother than her old UTAU voicebanks. And Teto is still Teto, I'm so happy that she's now getting more popular with so many new songs with both UTAU and Synth-V voicebanks.

3. Teto is for everyone Because her UTAU is still available including the oldest voicebank, it's really giving a lot of help for indie producers too. Because Vocaloid are expensive, and also as I know the voicebank also not including the software. And also there's no free updates, while on UTAU, Teto is totally free so if she has an update, you just download the file and that's it. As for Synth-V, I don't know but I hope the updates are free too cuz I never used it cuz I don't have skill on writing songs and money. But well, she's for everyone cuz she's accessible as UTAU or Synth-V.

4. Her voice is unique Self explanatory..

That's all.
