A few Vocal Synth s (a.k.a people that make covers) I like a lot, I tried to mention not so well known s.
This has no especific order btw
• JiLLY :P
This person truly knows how to use Rin and Len Act1, and also made one of the best uses of Hatsune Miku I've personally heard
I would describe their tuning as emotion-centered, and kind of realistic
At the moment most recent cover is Unhappy Refrain Ft. Kagamine Rin
And my personal favorites are; Yoru ni Kakeru Ft. Koharu Rikka, Hoshi no Uta Ft. Ken, Nonbreath Oblige Ft. Kagamine Len, True my Heart Ft. Kagamine Len, and, my favorite one, What's The Matter Luka Ft. Hatsune Miku
• Jakua-P
I would say this is the best Jinriki out there
Since they use Jinriki Utaus their tuning isn't that realistic, but stills good and their vbs are impressively smooth
At the moment their most recent cover is Bacterial Contamination Ft. Alastor
And my favorites of theirs are; the one I've mentioned before, Envy Baby Ft. Senpai, Alice Human Sacrifice Ft. Spinel, Wakko Warner, Blossom, Spongebob & Sandy, Daisy Bell Ft. Karamatsu and my favorite one could be considered as kind of problematic bc of the song, but after reading the description it was clear they didn't make with any other intention than to spread awareness. After clearing that up, the cover is Ruru's Suicide Show on a Livestream Ft. Ichimatsu
Best Ruko , needs more love
Really but really expressive tuning, Ruko literally screams her lungs and I love it
Most recent cover is Ai to Renbin Kaibutsu ni Onaji Ft. Yokune Ruko
And my favs are; Fixer Ft. Yokune Ruko, Android Girl Ft. Yokune Ruko, Bad ∞ End ∞ Night Ft. Anna Nui, Matsudappoine, Gahata Meiji, Matsudappoiyo, Miko Ooka, Rou Kemonone, Denatsu Sora, Kazuya Uehara & Galvan Ize, Venom Ft. Yokune Ruko, SIU Ft. Yokune Ruko, and the best one according to me, La Camisa Negra Ft. Yokune Ruko

I had never loved furries as much as I did after listening to neku's Utau
This guy's tuning is just something else, also Unmei Kazuki is really high quality
Most recent cover is Ivory Ft. Unmei Kazuki
And my favorites are; Ai Kotoba Ft. Unmei Kazuki & Ohne Kuno (this one was tuned by someone else but idc, it's still on his channel), Miracle Paint Ft. Mimi-YA, Egoist Ft. Unmei Kazuki (also tuned by someone else), Toosenbo Ft. Unmei Kazuki, Saihate Ft. MAT, and my fav, Lagtrain Ft. Unmei Kazuki
Ok this is the last one I'm talking about
Their tuning is just- :flushed:
It's so full of emotion and expression, pretty realistic and pleasent to hear, uses cryptonloids for most of their covers and makes them sound like pop stars
Most recent cover Kanade Tomosu Sora Ft. Hatsune Miku
Favorites; Until I Throw my Dreams Away And Become an Adult Ft. Kagamine Rin, Fragile Ft. Hatsune Miku & Kagamine Rin, GimmexGimme Ft. Kagamine Len & KAITO, Giants Ft. All Cryptonloids, GETCHA! Ft. Kagamine Len & KAITO, and according to me the best out of all of 'em, POP/STARS Ft. Hatsune Miku, Megurine Luka, MEIKO & Kagamine Rin

Earth Square is cool! I love their cover of Ready Steady with Kaito, Luka and Meiko!
Yeah they're really cool, I'd say they have one of the bests tuning skills out there, they deserve even more love
