I have triple boot installed on my mac (mac, linux, windows), and I find them all useful for different purposes. windows is the most accessible one for sure, so you don't have to struggle with finding a specific software etc. but I highly recommend trying out linux at least as a dual boot, as it's fully customizable and has many advantages compared to windows that I'd recommend looking into. mac has advantages as well, and has been the most stable one that has worked for me so far, (obviously , since it's the default OS).
