First off, what is a Linux distribution? This is what Wikipedia says:
A Linux distribution (often called a distro for short) is an operating system made as a software collection based on the Linux kernel and, often, on a package management system.
To put it bluntly, a distro is a Linux kernel plus some software. That's it. The software can be whatever the distro creator wants to distribute with that kernel. For example, some distros come with OpenOffice, some come with KOffice, while some come with LibreOffice.
Generally speaking, you can use any Linux compatible software on any Linux distribution (and even non Linux OSs like BSD). Kali is Debian based, as is Ubuntu. So you can easily install .deb
packages on either. However, you are not limited to .deb
, just about any Linux software should work. There are packages that will install .rpm
packages on Debian based systems.
This means, if you find Ubuntu, Mint, Red Hat, CentOS, Suse, (even BSD) etc a better environment to work in, you can install any software packages you find missing that were in Kali Linux.
As for your second question, that is purely opinion based. Again, generally speaking, you can put any Linux software on any distro, so one could argue that they are all equally useful. Some distros are packaged with less overhead, so they run faster than a more "bloated" distro. Some distros are designed to be a general user's desktop. Some distros package only open source software, while others include closed source. You just have to find, or create, the mix you find best meets your needs.

Kali's an Ubuntu fork
That is technically not true, because Kali Linux is a direct fork from Debian Testing and Ubuntu is a somewhat fork from Debian Stable. So Kali and Ubuntu are related to each other, but more in a silbling relationship than in a Parent/child type of relationship, each carry the same genes, but not the same just like silblings. – Nordlys Jeger – 2018-11-11T04:05:43.840
