If you get Solaria as your first female, you will find she is very versatile.
To decide which first male you would like, you should listen to each of either Hayden, Saros or Kevin, because they are quite different, and all good. Saros has a lot of different tone qualities, and can sing quite high, and is more for rock, pop. Hayden has a beautiful mellow raspy voice (sort of husky) and good for soulful country as well as very high male harmonies. Kevin is more traditional and some say a little "square" but has a very good track-cutting tone, and it is possible to make him sound like James Taylor.

Once you get good with the first two voices you will find that singers with quite different tone qualities work well for harmonies, because you can hear the distinctiveness of each so the group sounds bigger. Here is a track using four different male voices (acapella) on top of some women, and I like how I can hear the difference between tenor, baritone and bass:
