Well depends if your going to get the V3 of some of these vocaloids, Gumi's is out and there in the process of starting V3 Luka and VY2. So if you want to get those 2 you might wanna wait, Yuzuki Yukari can talk so she might be cool to have and she's not to popular so maybe you can make some awesome songs to get her going. Gumi V3 and native are out so you could do a lot with her. IA on the other hand is said to be one of the better vocaloid 3 and is good at holding out long notes. sorry I'm not much help because I can't chose one! Try looking on the vocaloid wiki see what music genres they specify in and how hard each is to use, not to mention finding sites to buy them from because vocaloid programs usually cost 200$+ if anything I suppose you can flip a coin lol. -><- Just get the vocaloid that will be the best at promoting your own personal style because that's kinda what their made for!

^Thanks, but that's the problem, I really can't choose, they're pretty much all my style, more on the Yuma or GUMI side though... and I'm not even sure if I'd want V3 or not, whichever version is easier to use... And then what sounds better. Thanks for the help though ^^

Getting a VOCALOID?! Wow... That's so impossible for me.. D:

I find it funny that the only two that haven't been voted for are my favorite. They're both my absolute favorite ._. XDD

I heard Yukari is one of the hardest vocaloids to use, though sounds pretty good. The vy's, I hear, are top-quality.

From what I know, Gumi's good for beginners, so... Yep.

^i'd like to disagree with that.
luka is from the most popular company. gumi and ia are two of the most popular non-crypton vocaloids. vy2 seems to have so many more fans than vy1 in the western fandom, quite a bit. yukari is one of the most popular v3s along with ia.

Vy2 Yuuma sounds amazing~! He is one of my very favorites ^^

Maybe next time you might consider Vy1 Mizki~
