They're pretty damn solid in all areas. Can't really think of anything I don't like about them
Love the site. The Favorites setup is great. Its quick, easy to get to the sport I want to make a play in. The lines are always organized by time of game. Bookmaker is a mess as far as oganization of games. No rotation numbers, not in order of time of kickoff/first pitch. I have to use a search to find a specific CFB game on Saturdays due to how many there are.
The only downside for BOL is that the lines for some sports aren't as favorable as other books.
Seems as though books specialize in sports and offer lowest price lines, which are a few cents off vs BOL.
These are general statements (not always the case):
Heritage --> Better MLB lines
Bookmaker --> Better CFB and NFL lines
etc....
One major sport BOL does not do well in at all --> Soccer.
Limited selections. Limited lines available. Limited games available.
