The only real difference I can think of is that Ubuntu’s installer is actually really nice and had the dual boot install option, which I don’t think any other distro has.
most distros that aren’t like slackware/gentoo/arch/etc. install with calamares these days, it handles dual boot configs simply and without issue. even doing like debian netinst, I don’t remember it having any trouble
