Mhm, that's interesting. I think that Willow has clearly more power. She is stronger than Tara. We saw that many times in BTVS. But this doesn't mean that Willow will win such a fight. It's just as it's in every fight. Not the one with the biggest muscles win, it's the one who can combine strength, endurance, skill, cunning and occur. If Tara is prepared I think she can play Willow out. She isn't stupid, she won't fight her face to face. She would bring some tricks. Willow is too much self-confidnece. And that's why she "could" walk into a trap. I think there is all open, both could win.
