Much safer?

When the Ledger recover fiasco unfolded last year, I decided to migrate my BTC to a bitcoin only hardware wallet, Bitbox02 to be specific. Since I've had it which is about a year now, the only transactions I've made are deposits from the exchange to the wallet via the xpub with electrum. It's a "watch only" wallet in electrum. So since I've never signed a transaction ever. Is my private key safer than it would be if I would have signed/ sent transactions?
