Electrum is a great wallet, especially the desktop version. But it can be a bit intimidating for new users. It's got a lot of features that basically makes it a Swiss Army Knife, but those functions are often hid behind different screens and menus, so it can be difficult to find what you're looking for. The mobile version is a bit more scaled back, and focuses on core functionality, but even so, it's not as friendly and intuitive as many other wallets. I consider it a power user wallet, along with Mycelium, and Sparrow. It's all about finding the one that you're most comfortable with as they all do what you need.
