Electrum wallet is the best wallet I have used so far. Its lightweight the design is user friendly and you can adjust the fee's. Specially with the current situation, adjusting fee's is a must because if you like to transfer bitcoin quick then you will love this feature.
Same here, I'm also using electrum wallet, it is like a hardware wallet since it could go offline, and that is safe for me since it is not that vulnerable to the hackers compare to the web wallets out there.
