When stake really got big was the time it had sportsbook, I would suggest you to check it, they have nice odds as well. The great thing about stake is the fact that they listen to their customers, when the sportsbook first started I have to be honest it didn't look good, it looked quite horrible in fact, and it had a ton of bugs and glitches and troubles.
The addition of a sports book which everyone was waiting for years was a very good move but they were big enough with multiple games and huge rollers can be seen wagging all the time. Not sure what major changes they made with the sportsbook after the launch as i could not find much of a difference. I can understand the bugs and glitches when rolling out for the first time but is there any major change in UI?.
