Actually from the female view point right now in romantic literature, the beta male (think accountant, wears glasses, isn't physical) has a lot of fans. I know that there are a lot of fan fic authors that write Chakotay as the "alpha" male type, but I find nothing wrong with the "beta" Chakotay we saw most often on Voyager.
I would never personally go above beta

Chakotay was plenty Alpha in Caretaker. Honestly I think Jeri Taylor just toned him way back because she didn't want him stealing Janeway's spotlight.
He looked good in those leathers too.
