I use web wallet and I prefer to use it that other wallets listed because I can see it is safest in my part, unlike hardware wallet though it is stated that it is safest once your computer hacks with some other hackers your wallet is in danger also when you reformat your computer unexpectedly it is a bye bye coins. Web wallet is easier to use, you can access it whenever or wherever you are, but then fees might vary of this because it increases too. But it is up to you where you can easily access your coin..
Any wallet you have that is on any website is super vulnerable to all kinds of attacks, I would highly suggest you to take them off now. For one thing, typing out your private keys to access your wallet all the time is an insanely bad idea because of the fact that there could be key loggers on your device recording your private keys and stealing them without you knowing. Or better yet, they could log your password to get into your wallet as well... not to mention that I'm pretty sure all web wallets have your private keys; so if you aren't the only one who is in control of your private keys, you don't necessarily "own" your coins.
There are just so many security vulnerabilities, that it just sounds like that is just a bad idea to have everything you own on a web wallet. I know it's "convenient", but Bitcoin suggests and proposes the idea to let you "be your own bank" for a reason.
