I score the support team on responsiveness and on whether the answer actually solves the problem, because customer support is the part of a casino you only notice when something goes wrong. I also check how deep the game selection runs inside each vertical, because a lobby of thousands of titles drawn from a handful of studios is narrower than it first looks. Withdrawal speed carries the most weight here, with the highest marks for payouts inside 24 hours and lower marks as processing stretches towards several business days. Most protections are mandatory for UKGC-licensed sites, so I do not score them as simply present or absent. A reduced build and a wagering requirement are the same problem arriving twice. It compounds with wagering too.
