Not BetOnSports, not this time of year. It's all spent on radio which they are cancelling like mad after the squares took them to the cleaners.
It's a good qusetion. A lot of Pinnacle is still credit so I wouldn't bet against WWTS in that matchup.
Just including books that cater to US players I would go:
Sportingbet
Bet365
WWTS
Canbet
Pinnacle
VIP group
SI
