The right choice depends on your use case. Consider: which chain do you need? USDT is available on 130 chains and USDX on 3. What backing do you prefer? What's your integration surface (exchanges, DeFi protocols, payment providers)? Both have deep liquidity, so market cap alone shouldn't decide it.
