The 13-point WCI gap is real, just not large. Rollbit 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.
Rollbit runs a zero-rollover welcome, which is the unusual variable here. Zero rollover means winnings from the bonus convert to cash on the first qualifying bet rather than after multiple replays of the bonus value. That makes the Rollbit offer the higher expected-value pick even before you compare the headline numbers.
Where the two brands actually diverge on product: licence (Anjouan Gaming (ALSI-132404028-FI3) versus Curaçao Gaming Authority (sub-licence under Curaçao master licence)) and operating history (Rollbit 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 Rollbit. WCI 78 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.
