Who should I get on the next sale?

[Bookworm2]

I'm having a tough time choosing which voicebank to get when Zero-G next has a sale on their Vocaloids. I'm of course going to get the queen AVANNA but if I have any extra cash I'm thinking of getting one of their V2 voicebanks before they get discontinued.

Potential pros and cons of each:

TONIO

Pros:
Male voice in English
Operatic voice (I can use this)
From what I've heard, pretty good pronunciation

Cons:
@ phonetic glitch
Hard to use in non-opera genres
Kinda unstable (from what I've heard)

PRIMA

Pros:
QUEEN voice
Operatic voice
Really really really pretty tone
Surprisingly understandable for one of the first V2 banks

Cons:
Hard to use in non-opera genres
Like REALLY hard to use in non-opera genres
Unstable
I don't really need another female voice

SONIKA

Pros:
Unique pop tone
(Supposed) Language compatibility

Cons:
Hard to use
REALLY hard to use
Low-quality
REALLY low-quality
Muffled
I don't really need another female voice
Unstable

So if any of you could give suggestions, that would be amazing!
