Pro Recoverable by seed
Electrum is a hierarchical deterministic wallet meaning both public and private keys are derived from a seed. In case the wallet needs to be recovered, you can do that using the seed. Electrum uses a 12-word mnemonic passphrase and asks you to re-enter the seed the first time it generates the keys to make sure you understand the process.

Con You have to trust Electrum servers
As with all thin clients, you have to put some amount of trust in the servers that the wallet connects to for verification.
