Lately, I've been debating whether to use L2 or the mainnet. Honestly, it's about trading gas for certainty, and trading a little hidden cost for a better experience—so they don't steal from you. For small, frequent transactions, I usually go with L2. If I do the math of bridging funds twice, spread over each transaction, don’t just focus on “single transaction being cheap.” If I need to make large transfers or involve sensitive permissions/contracts, I’d rather spend a bit more on the mainnet to avoid getting stuck on bridges or waiting half a day for cross-chain messages.

Another point is, don’t be too superstitious about on-chain data tools’ tagging systems. Recently, someone was complaining about lag and being misled. Anyway, when I calculate real returns, I always include “deposits/withdrawals/bridges/failed transactions” as costs. I only trust data that matches my wallet flow; pretty charts are useless.
