The main strength of Bet365 is the live betting. Loading speeds are fast, and odds are constantly updated, so it isn't hard to place live bets, unlike elsewhere.

• BetRivers legal states: AZ, CO, DE, IN, IA, IL, LA, MD, MI, NJ, NY, OH, PA, VA, WV
  

While BetRivers may not have as big of a brand name compared to the betting sites listed so far, it has become the best out of the second tier of online sportsbooks.

BetRivers offers its iRush loyalty program which is one of the better rewards systems out of all betting sites. We recommend BetRivers as a secondary sportsbook to those who are looking for extra profit boosts and daily bonuses.

• Hard Rock Bet Legal States: AZ, CO, FL, IL, IN, MI, NJ, OH, TN, VA

Hard Rock Bet is a very solid betting site in the same tier as BetRivers. It's the only online sportsbook available in Florida, so thankfully, Florida sports bettors have a good option.

Though not quite on the same level as our top 5, Hard Rock Bet offers many key features to look for in a sports betting site, such as daily odds boosts and even live streaming for select sports.

• Bally Bet legal states: AZ, CO, IN, IA, MD, MA, NJ, NY, OH, TN, VA
