The "life" of the Vocaloid (if what you mean is how "human" they sound, personality, emotion, etc.) is dependant heavily on the perosn programming it... but if you're refering to things like power (like getting louder and quieter) I haven't seen an issue with Luka or GUMI, but not nearly has powerful as MEIKO V3.

Anyway, to answer you're question I've found that Rin and Miku sound similar but many have disagreed, just as I don't really hear the similarities between GUMI and Luka that much.

If you are looking for a voice similar Vocaloid in particular, they'd I just expose myself to as many Vocaloid as I can, and then you'd find someone. ^^

If you're just curious about others, then personally I think, Gakupo and KAITO are decently similar, and Rin and Miku. I have others but I can't really think of them.
