Is there any significant difference between them? As far as I'm aware most bridges works the same. Not to mention most layer-2 offers swap from the get-go.
I remember bridging my ETH to various networks like Base, Solana, etc in the past. Can't recall any significant service fees. Unless I somehow stumbled upon a scam website.
The difference is on the fees and slippage. Some bridges have no deep liquidity and big fees. In result, when you're bridging your money use the bridge with no deep liq and big fees, your money will be deducted significantly.
If you're only bridging small money, it won't affect you. However, if you're bridging like 4, 5, 6 figures or even more. It will decrease your money a lot due to slippage & fees.
