Not sure if it's the best above whatever else, but I know electrum is a very good bitcoin wallet. Positive points:
1) 100% free non-custodial wallet
2) being a non custodial wallet means you own the private keys
3) you can install electrum in as many devices as you want (don't lose the seed, you'll need it to recover your electrum wallet if your ancient device get broken and there is the need to install electrum in a new machine)
Electrum wallet is good for users who don't own too many satoshis, so the expense to buy a trezor or a ledger (these are physical cold wallets, really considered the absolute best, but it's expensive and the purchase is worth only if it's smaller than your amount of satoshis.
