Being a professional player myself, relying on a Casinos ability for swift and secure withdrawals I have to this date probably gone through most online casinos with live dealers.
There are to days date only two casinos that carry, what I call, a perfect service for online professional roulette players,
The first one is Dublinbet that uses the famous fitzwilliams casino as a proxy for its live dealer casino broadcasting. They also use the studio casino packages provided by NETENT and Evolution which are not to recommend as their betwindow is too short for serious play.
The other one, and my favourite, is portomasolive which is a beautiful Casino based on Malta at S:t Julians
I have earned thousands of euro this year playing in this Casino in its top notch online platforms that offers real pro-tables with real players and HD video broadcasting for those that cannot visit their facility on Malta).

here you can see what they offer

and here is how the tables look like:


All in all, it can be said that todays "industry standard" for betwindows (spin to spin window for betting) are very low in most online casinos that use standard platforms like NETENT and Evolution (the latter being the lowest).
Casinos like Dublinbet and Portomaso have their own excellent platforms and their players enjoy betwindows and a serious game with betwindows between 30sek and up to several minutes depending on how much ppl are at the tables. For an online player that is perfect as to test various strategies and platforms demanding certain time of thought and strategythinking.
When it comes to cheating software, on roulette, I can only say that certain, less serious casinos, use it in various ways and also by using "lega actions", like net-congestion, faster closing of betwindow than what the countdown clock shows on the platform, refusal of withdrawals due to certain obscure causes they deem right, and of course other ways to induce stress in a player that tend to win too much.
Finding good online casinos is an art, and the few available are real treasures for the professional player making a good living on them or at least a good extra income beyond his or hers normal income.
Hope this helps.
