WDC for me.... a number of factors differentiate this coin from others
1) The name "WorldCoin" - not named after an animal, mineral or vegetable. The brand is sound.
2) Support structure - the forums and the people are very supportive and work together in support of the coin and wider alt community.
3) Infrastructure - Wallet, Mobile Phone apps, direct usd to wdc exchange capability with a range of payment methodologies. This gives a great access route into crypto.
4) The board - Very down to earth individuals who actually listen and consult.
5) Legal - They have legal counsel. Everything is above board. FinCEN membership.
6) Excellent AML procedures - To me, this differentiates serious businesses from fly-by-night operations.
7) Great liquidity and range of markets - easy to get into, easy to get out of

Merchant tools - another important requirement for serious cryptocurrencies. Bottom line is a currency is used to buy and sell good and services. Its doin what its supposed to.
9) Kanye West has nothing to do with this coin at all.
10) Finally, has done great charity work
AAA transaction speed.... i have spent over an hour waiting for btc to clear into an exchange.... soooo frustrating. WDC is very fast in comparison.
