L2beat.com has an overview of rollups and involved risks.
Arbitrum ranks pretty high on safety and also has the most TVL, so it’s a good place for DeFi.
Optimism is considered the other one of the big 2 optimistic rollups, and even though it’s not as technically secure, they’ve been running fine for a couple years now.
The safest way to bridge back and forth to Arbitrum or Optimism is to use their official bridges. Note there is a 7 day waiting period on bridging back to Ethereum mainnet. The Optimism bridge back may also require 2 steps.
If you use thirdparty bridges, the fees are likely to be higher and they’re less secure. So I would never use a thirdparty bridge from Ethereum to Arb/Op, but I occasionally use a thirdparty bridge back to Ethereum in order to avoid the week-long wait.
