Personally, I used Electrum for BTC. It is a compact installation and does not need to download the blockchain (as with bitcoin is huge now after many years of transactions  ). It connects through the blockchain via remote connection to a blockchain explorer. In my experiences, its very easy and very quick to use. And as long as you secure your wallet code, which is a string of words unique to your wallet, it is very forgiving, should you forget your encryption key, all you have to do is create a "new" wallet using your original wallet code and you have your wallet back sans encryption code. That is why it is extremely important to secure your code, as anyone with it can do the same thing.   

However, I do use other wallets besides Electrum. I have a xapo wallet, however, in my experiences is only really good for things like faucets and gambling where they offer direct pay and/or bonues for using a xapo wallet. There is multiple layers of passwords and confirmations that can sometimes make it a hassle to access your coin quickly. I usually end up flushing my xapo wallet into my electrum wallet every few weeks so that I have better access to my coin.
