Been to both, don't know if it really matters.
If you haven't done a bunch of tours before, try not to get hammered too early. It's surprising how it seems you're not drinking much, but you leave a cool cellar and step out into 105F heat and wham.
I don't know any of the newer restaurants cited here. Many I was familiar with are gone. But I'll always recommend Mustard's. That place (and its Mongolian pork chop) has stood the test of time, and you're not getting a reservation at TFL at this point.
I would strongly recommend trying to get into
Jarvis winery (Healdsburg) if you can. You can get tired of the same old kinds of tours, but not this one. The whole operation was drilled out of a small mountain. The owners were oddballs. Not sure if they still have the his & her bedrooms as part of the tour, but it was definitely one of the weirdest wineries and histories I've ever seen. And the wines are solid - we shipped back 3 cases last visit.
I'd also make a point to hit Chateau Montelena, especially if you like big wines.
