imho, there's very little difference, size-wise between a 5gal and 10 gal -- go for the latter.
I'd say double the water volume is a pretty big difference....
That being said, unless she has really soft water five blue male guppies in a planted 10 gal could be a really nice setup. Most other blue fish are shoaling fish, and the ones that can fit in a 10 gal are pretty sensitive and by no means low-maintenance. You should really try to convince her to get a betta in a 5 or 10 gal as that honestly seems like the best option to me.
