Lately I keep seeing everyone arguing about which L2 has higher TPS, lower fees, and bigger subsidies. To be honest, I care more about whether my transaction might be casually snatched into a bundle and exploited. Retail investors don't need to understand the deep mechanics of block builders; just remember roughly: the transaction you send out may not be included in the block in the order you want, others can bundle a series of transactions together, and front-running/sniping often happens this way.

My personal bottom line is: for large swaps and cross-chain transactions, I prefer to spend a bit more time splitting them into two transactions or use routes with some protection, even if the fees are a bit higher; and also try not to use setups that blindly set the highest slippage with one-click swaps. Anyway, I’ve tested bridges a lot, and saving a few cents only to have it snatched away makes my mood worse… Let’s leave it at that for now.
