I am a Windows Insider and also a tinkerer, and figured that if I'm going to test the OS for Microsoft, I want the SKU which includes absolutely every feature. Because why not? Which SKU is that?
I don't think you really needed it, if you, or the OP, don't have the specific hardware it's made for, normal enterprise or education will be best but pro will do just fine for most. And the OP can easily switch between all SKUs (pro and up) as many times as they want, to test all SKUs anyway.
Thanks everyone for your replies. Ended up choosing Enterprise x64 as my daily driver as it seems to be the absolute greatest SKU in terms of features...
