Like some have mentioned, if you want to try different distros setup a VM (I would recommend KVM for better performance, but virtualbox is easier for beginners in VMing) with the iso of the distro you want to test out.
Like this you can keep a functional system without the hassle of having to setup on baremetal just for testing and having to go back again if doesn't pay-out.
Also would suggest messing around with more tech-savy setups like debian and fedora (specially minimal ones) if you want to delve deeper into the Linux nerdiness.
