If your after a good English vocal, then your not after either, as Diva and Songman are better, followed by Dex and Daina.

Out of the pair, its difficult. On the one hand, Miku V4 has a shallow vocal range, so can't sing as good. On the other Gumi English is kinda buggy. Miku English doesn't match to her Japanese counterparts in capabilities, while Gumi does, but both still have issues to do with their accent. Gumi also doesn't have XSY or GWL, while Miku V4 can XSY with V3 English and has GWL.

CFM English vocals in particular aren't great as they tend to toss out them for the sake of having them available and their often the bare minimum needed to be worth even considering, one octave approx. I understand why they do this, due to English being a lower profit and all that... But it never looks good when it comes to fans really being critical, and all of their vocals have issues that often the same throughout their catalog... IT gets to the point wherein the Japanese vocals are only really worth looking at and the English are just there. Even down to the fact their not really aimed at us... Their existence is for Japanese producers to be able to break into the English market (worst confession of a company ever, along with calling Miku English "project Mikucash").

In due respects, I tend to be a bit bias and lean towards Gumi because of this as its the better vocal despite the bugs... And honestly? Once you get used to beating Vocaloid bugs they aren't so much of a problem anymore. It just takes used to getting to know what to expect. Considering all Voicebanks more or less have their fair share of faults and bugs, its not a big deal. True some cannot be fixed, but at least Gumi English more or less is an approx. for her Japanese vocal. :-/

In the end... You may be better off waiting, as there may be a Gumi update for all we know and waiting has never hurt anyone. This is why I often list it as a option, as within a year a game changing vocal can be released that is exactly what everyone wanted. Plus we're getting late into V4 now and there is tops about a year left of its life cycle... With V5 so close around the corner, there is this too to bare in mind.
