If you count out RTP there is no such thing as "better" wins, hitting a 1000x win and then 1000 losses is just as bad as hitting ten x2 and then ten 10 losses, one is exciting as hell and makes you hunt that jackpot then drive you to dispair the other is as boring as a 50/50 dice game but in the end the result will be the same.

Plus, taking into account individual experience is resembling a bit chasing "hot and cold" machines  
What are you actually searching for, slots that are profitable, lol?
