Bookmaker, Pinnacle and BOL are in a class by themselves offshore.
No one even close.
Every other book offshore moves on air when these 3 books move.
They post their own lines, book to action and understand how to handle sharper action.
Every other book delays, limits, boots and/or copies lines because they don't have the bookmaking talent of the 3 I mentioned.
Heritage and Bet105 would be 2nd tier as they run a good book but they obviously run a script to calculate and post the average line of the big boys.
BAS is nowhere near top tier with their sleazy delay and reject behavior.
GTbets just copies lines and kicks out winners.
Bovada originates and uses there own lines but limits or boots anyone who wins.
BetUS is one of the sleaziest books there is. They stiffed me, and others.
