I would say that Electrum is one of the best wallets I've ever used, through the UI seems kinda old to me but the performance is superb. What I like about this wallet is it is open source and it has no hidden program just like other wallets have. But if you are into safety and you also do have some spare funds you could probably be taking a hardware wallet for better security. Electrum is not limited to your computer but also can be used through your mobile phone giving convenience to the user. However, you should not only stick to a single wallet you could also try to use other trusted wallets maybe that could suit your taste.
