The one thing I've really noticed recently, and only recently - bizarrely (despite 2.5 years of S ownership), is that you sit waaaay higher in the S than in the 3. Or maybe it's just the windshield location on the S, but as a tall human (~6'6") I wish I sat lower in the S, like you do in the 3. The 3's seating position is leaaaaagues better than the S. That's part of why the S feels like such a boat, - you sit so much higher in relation to the windshield. This means, for me at least, the sun vizors are kind of in the way and I find myself scooting down in the seat as much as possible to recreate the Model 3 feel.
