This is not about the wallet that you are using, it is about your seed phrase which is used to access your coins. Make sure you protect the seed phrase.
About wallets, the safest are paper wallet if you operate it offline, and wallet on airgapped devices. Next to a reputed hardware wallet.which is also secure.
Centralized exchanges are not reliable. Not your key not your coin.
