Aquarius or Virgo...Better Match?

For a Scorpio woman, who is the better match the Virgo male or the Aquarius male.
I only ask because I am pursuing a Scorpio woman, and feel as if I'm competing with an Aquarius male for her.
She seems to be moe intrigued with him but more at ease and fulfilled withme.
Is this one of those things where they have more basic flash in the pan attraction, and me and her have more long-term compatibility?
Kind of like the difference between a Virgo males relationship with a Cappy woman vs a Pisces woman...we'll probably become romantically involved quicker with the Pisces but end up with the Cappy.

Anyways, let me know, because I'm not going to get emotionally invested in this, if he is more of her match than me. I'm also not going to play bitch-on-deck, or try to push him out, as I'm past that kind of mentality.

What does 4-10 thing mean?

I think Virgo would be better, but Aquarius will give her more excitement and thrills and keep her coming back.
