Best Methods to Move ETH Between Networks Efficiently?

Hi everyone! I’ve been exploring ways to move my ETH around without getting hit by high fees or slow confirmations. I mostly use Ethereum L2 networks, but sometimes I need to get my assets over to another chain quickly for trading or DeFi opportunities. I’ve heard about different bridging methods, but it’s hard to figure out which ones are actually reliable and fast. Has anyone tried moving ETH between Base and Polygon? Curious about the process, fees, and whether it feels secure for regular use. Thanks in advance for your insights!
