BitcoinAccepted asked for people to share their experience, here is mine after creating an account not long ago.
Layout: C, the site has a clean layout but is kinda clunky and a little slow, it lacks some basic info like a page to show if your withdrawl was already approved, i found a visual bug where the numbers simply disappear when trying to bet O/U goals, it's also extremelly annoying how every time you open a new tab you have to choose a coin for the site to convert to so you can bet despite having it already set in my configuration page.
Deposit: S, instantaneous with my e-wallet.
Withdrawl: B, here i had a big problem but i can understand why, my e-wallet was just recently added and it looks like everything wasn't working 100% so the withdrawls were delayed, but after it was fixed things started working well, the withdrawl itself takes around 12 hours, not the fastest but not bad.
Coins: B+, A lot of options and you can use FIAT, the problem is when you deposit BRL it will automatically convert to USD, i wish i could just use BRL.
Bonus: D-, I don't like deposit bonus so i can't comment on that, but they have a very strange boosted odds system, when i asked the live chat support said that you have to request the boosted odds AFTER the bet is settled, wich sounds VERY strange and laborious to me, i've tried 3 times but they all lost so i don't know what will really happen, but i have a strong gut feeling that this won't even work, i expected them to say "no it's not like that" or "you've got it wrong" or something like that.
Betting Limits: F-, Playbetr is without any doubt one of the worst experiences that i've ever had when it comes to betting limits. I love CSGO, and the biggest tournament of the year is happen right now, do you know how much they let me bet? 8 fucking dollars, that PATHETIC, why would even open a market to let people bet 8 dollars?
Odds: A, great odds.
Support: B+, live chat is just ok compared to the best sites, they take some time to answer, but in general they were very attentive in solving the e-wallet problem i've described before.
I consider them a C+/B sportsbooks in general, but if they don't fix these betting limits it's just impossible for me to use their services.
