Verdict
The clearest difference is in-app purchases: usdc.cool at none against USDT Signal's 1. usdc.cool also leads on ads (none vs shown). USDT Signal's advantage is update cadence (weekly vs every 3 months) and iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.
