These days, I've been switching back and forth between several L2s, and my feeling is: the mainnet is like a highway, stable but with really expensive tolls; L2s are like city expressways, cheap and convenient but sometimes detour. I think ordinary people shouldn't worry about "pure mainnet/pure L2," for small daily transactions, put them on L2; if you really want to move large amounts long-term or are worried about bridge issues, just stay on the mainnet and pay the fees as insurance. Now there are a bunch of testnet incentives, token expectations, and daily guesses in the group about whether the mainnet will issue tokens... (Honestly, I only care about not having to pay for two meals for one interaction) Anyway, my compromise is: first, put frequently used funds on L2; after using them, withdraw some back to the mainnet; don’t gamble on both experience and security in one place.
