I started with The Way of Kings in late 2016 recommended by a colleague- I think for most of us the first book will always have a special place. I then read Words of Radiance, the Mistborn ones and then caught up the rest before Oathbringer. Aside from a few obvious highlights in the main Stormlight books my favourite is the ending to Warbringer.
It hasn't been a good pandemic experience so far, happy to get back to reading in general- enjoyed taking two days off at the end of last week to dedicate some time to WoR.
It's interesting to think about a possible different reading experience/ starting point, knowing how some of the pieces fit together.
I wouldn't change anything but if I had read Mistborn 1-3 before WoR had been released that could have made for a very interesting experience.
