Blockchain.com wallet is a web wallet which is far less secure than a software wallet like Electrum. Regarding the easiness of using, it's pretty easy as like as send/receive sounds. I never found it as a complex one.
You can use Hardware wallet for maximum security. Be aware choosing the best one, don't buy from any unofficial source.
BTC wallets is actually very easy to use, but many people have trouble with it. This is easily fixed. You just need to use it for a while, having studied slowly and sequentially all the functions. Having mastered and got used to wallet, it will no longer seem like something difficult. The simplest and most reliable is electrum. In conjunction with hardware wallet, reliability increases, but it will take a little effort to master HW too. Nothing complicated, but the first time there may be a hitch. There is nothing wrong with that, and with cryptocurrencies one way or another you will need to learn new things, because the industry is new and rapidly changing.
Blockchain.com I wouldn't use. Despite its apparent simplicity, this website can cause more headaches for beginners than electrum. Also consider less reliability and the fact that Blockchain.com limits and stops serving certain regions. This doesn't fit in with the idea of freedom, which is cultivated in the world of cryptocurrencies.
