Which two albums represent Stevie's best Fleetwood Mac work?

I think Stevie was actually underutilized on the White Album. It probably has to do with her having far less of a say, understandably, in the creative decisions. Rhiannon's definitely the most important song of the three. I'm still wondering whether Stevie was forced to hand Crystal over to Lindsey for his vocal or if the band enjoyed his sound from Buckingham Nicks. I would love to hear what Stevie's 1975 voice would sound like singing that song. I prefer Lindsey's vocal when comparing to Stevie's Practical Magic version.
