I don't like QR codes, because they are more vulnerable than keys. For example, whenever I activate my 2FA, I always write down my 2FA codes, and don't save QR codes. Maybe, I mainly want to give attackers, if they find me, and my wallet/2FA backups; they have to play around and maybe lost directions before being able to hack my money. QR codes might give them more convenience to do their works.
Well said mate, but here is my addition that might not lead to hacking if the device infected by malware copy/paste.
If there is QR code for that address you can simply scan for sending the address, no need copypasting of wallet address just tap the QR code.

Well explanation. I did not know about that, and from your explanation, I will search to find out more about it. Crypto always have loads of things to learn, everyday.
Why not check all characters/ digits of address? I think it is safer than only check first and last ones? Or are there some technical reasons for this?
Checking all characters/digits of address requires less than a minute, so I think people should check them all after adopting and pasting.
It is impossible for a hacker to generate a private key which only changes a few digits of your public address.
Even vanity generators are able only to match a few characters together.
So you only need to check some characters, not all of them.
Even if it takes only a minute, it is not necessary imo.
