RD - given that it's a SC, I think a solid navy or brown knit would just hit the spot. It's not that your wool tie looks bad with the SC, it's just a tad more dressy. Wearing a knit instead makes the shirt a little less out of place.
The top stitching is way too close to the edge of the collar & cuffs, imo. I like 1/4", I even have some 1/8", but those are pushing it.

It's supposed to be advantageous in that it avoids the edge curling you sometimes see on shirt collars. You can stick a collar stay right to the edge, after all. I think Kabbaz has also said it "lengthens" the collar by making it look larger without actually having to add any extra material. I'll be honest and say I'm a bit more skeptical of that claim, but perhaps it can depend on the type of stitch count and fabric we're comparing this against.
