I know exactly what you mean, those big brands get so complacent once they have millions of users. I switched to some smaller, fully regulated UK sites last month and the experience has been miles better, especially the customer support. To find them without risking my data, I checked out the breakdowns on https://llanelliscarlets.co.uk/welsh-casinos/ because they specialize in vetting independent and Welsh-focused casino brands. They have a really solid breakdown of what makes each operator worth it, including game variety and how fast they actually process withdrawals (which is my main pet peeve). It definitely helped me find a couple of hidden gems that don’t spam you with annoying ads every five minutes.
