Debian/Mint retains one previous release of the kernel as a backup in case you can't boot from the current kernel, in the menus you will see previous kernel selection

--however, although it wont save much file space, you can delete the unused kernel from your system
check /boot and /usr/src
--where you will find the previous kernel versions..
There is really no preferred method, except that Mint might present some as more suitable or emphasized, eg mint utilties (mintupdate, mininstall) etc..
I use synaptic mint menu>Package manager
, for application installs
--I used mintinstall at installation time, to see what were the recommended applications..Computer Janitor
--in mint menu>control center>system>Computer janitor
, will clean up uninstalled applicationsKernels../boot
, contains a few kernels , the same as appear on the mint menu at /boot/grub/menu.1st, if you had many kernels there you could remove/delte the one that don't appear on your mint menu (if you remove those, that menu entry wouldn't work,and you might have removed a critical kernel), such as the one you are using to boot the system, so you have to be careful about what you delete..You can install bleachbit
, this cleans up user or system /tmp and history residue and some applications data..
