The 10-point WCI gap is real, just not large. Gamdom edges Jack on the formula, mostly through the reserves and payout components rather than the age or licence ones. Both are within the band where a deposit-tester can recommend either, but if you only deposit once and never look at the leaderboard again, the higher number is the safer default.
Where the two brands actually diverge on product: licence (Curaçao Gaming Authority (OGL/2023/981/0450) versus Curaçao Gaming Control Board, License OGL/2024/1800/1049) and operating history (Gamdom is the older book by several years). Those are the axes that should decide the pick if the WCI gap is small. None of them shows up in the welcome banner, which is the operator preference, not the player one.
Take Gamdom as the default. WCI 70 against 60 is inside the margin where either operator is defensible, but the higher score is the higher score. Take Jack if you specifically want 100 wager-free spins on Book of Dead, no-KYC up to $5k, full sportsbook with AU racing. and you have read the trade-off in Jack's review. Both pay out. Both were deposit-tested by us this quarter.
