Signet's reliability is the actual feature worth calling out. Testnet3 blocks can come in bursts of hundreds per minute when someone mines with low difficulty — makes any timing-dependent test useless.
Signet's signed blocks guarantee ~10min cadence, so fee estimation, HTLC timeout logic, and CSV locktime behavior actually mirror mainnet. For anyone building payment channels or time-locked contracts, that consistency is worth more than the coins being free.
