I just brewed a cup of oolong tea, and casually switched back and forth between the mainnet and several L2s to check the depth... Honestly, my current compromise is pretty basic: small amounts, frequent operations, so I avoid L2, saving on gas and hassle; if I really need to do something "error-proof" (like large swaps, loan repayments, or migrating contract permissions), I’d rather spend a bit more gas to go back to the mainnet, at least I feel more secure.

And don’t get carried away by the user experience: L2s are indeed smooth, but the moment you bridge back and forth is the easiest way to get impatient, and you might start clicking randomly during confirmation delays. Recently, new chains are incentivizing TVL growth, and old users complain about “mining, arbitrage, and selling,” which I can understand too—liquidity gets thin when it heats up, and when the price gap widens, those chasing in feel the worst. Anyway, I focus on two things: whether the pool you’re using is deep enough, and whether the deposit and withdrawal channels are smooth—don’t save a few bucks on gas only to make your costs higher.
