Same brands, same weights, two different answers. The numbers below are deposit-tested and the scores recompute every build.

The 5-point WCI gap is real, just not large. Duel edges Sportsbet.io 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.
On the headline number, Duel caps the welcome at $1,000 against $300 at Sportsbet.io. The bigger banner does not always survive contact with the rollover. Duel runs a 35 rollover, Sportsbet.io runs 10. Multiply the cap by the rollover number if you want the wagering you actually have to put through to keep the money. Most people do that math after the deposit, which is the wrong order.
Coin breadth: Sportsbet.io accepts 12 cryptos against 8 at Duel. If you hold something past the top five, the breadth matters at deposit time and at withdrawal time. If you only ever move USDT or BTC, the breadth is a feature you do not use, and the count is irrelevant.
Where the two brands actually diverge on product: licence (Anjouan Gaming (ALSI-132404028-FI3) versus Curaçao Gaming Authority, License OGL/2023/110/0072), operating history (Sportsbet.io is the older book by several years), and live streaming (only Sportsbet.io 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 Duel as the default. WCI 65 against 60 is inside the margin where either operator is defensible, but the higher score is the higher score. Take Sportsbet.io if you specifically want Established crypto sportsbook since 2016, deep football, Bet Builder, mobile APK. and you have read the trade-off in Sportsbet.io's review. Both pay out. Both were deposit-tested by us this quarter.
