I always using desktop wallet. It wallet easy to use and i think its more secure wallet. I prefer you can always use desktop wallet that wallet more secure & safe.
You said that wallet is very easy to use on desktop, yes it is true that it is very easy to use any wallet on desktop but you also say that using wallet on desktop is safer than all. It just depends on the plate you are using because its application is the most secure if hard security is complete and if not then full of risk.
Not everyone like you has a desktop so it is not possible for everyone to use a desktop wallet.
I am a mobile user. I use Trust Wallet all the time. And the two most secure mobile wallets I have seen are the multiple wallets: Trust wallet, Metamask wallet.
