The 12-point WCI gap is real, just not large. Rainbet edges Duel 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 (Anjouan Gaming (ALSI-132404028-FI3) versus Curaçao Gaming Authority (OGL/2024/1124/0801)) and live streaming (only Rainbet carries it). 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 Rainbet. WCI 77 against 65 is not a close score. On withdrawal speed, on rollover terms, on coin breadth, the gap is large enough that the smaller-volume player and the heavier-volume player both end up at the same answer. Duel is the right pick only if it offers a specific bonus structure or product range you cannot get elsewhere, and on the brands we test, that case is rare.
