Electrum is one of the oldest btc wallet it is attributes rich but it is not user friendly. If you are just a beginner and newbie like me I suggest you to avoid electrum, but if youre familiar with the basic terms then this is the excellent selection for you to use.
How is Electrum not user friendly? It's much more user friendly compared to Core, because it has mnemonic seeds, ability to create signed transactions in GUI, easy coin control, and so on. It's all really easy and intuitive, Electrum is a good wallet for beginners, if I were to recommend a wallet to a newbie, I'd recommend Electrum.
The characteristics of Electrum is on being fast, safe and private.
Not true, Electrum is not private, since it relies on servers, and those servers can monitor your transactions. If you want privacy, run your own private Electrum server or just use Bitcoin Core.
