I'm glad you like the look. I was pretty happy with the final result. It actually took me several tries. On one of those tries, I ended with the VF scotchbrite, which made an even finer finish. Though scotchbrite is a little weird. It's almost like a shine on top of an existing finish. Or maybe a satin coating on top of your finish. It mellows out the grind lines from the earlier belts, and kind of smooths everything over. It really is a nice finish as you have said.
That belt you linked from TruGrit is *definitely* the gray "super fine" scotchbrite 1x42. I know because I just received one last week. Note that the description says "Medium", but the part number has "SFN" in it. That's the gray super fine for sure. I have not even put it on the machine yet, but I have it and plan to do some experiments with it.
Equivalent grit, as most here probably know, is a weird estimated thing. Because abrasives are all different shapes and configurations. ...and in the case of Scotchbrite, it's a combo abrasive with a soft mild cut, mixed with real abrasive particles bonded to that backing. But not very many of them (abrasive particles) as compared to a real belt. So it makes an unusual (but nice) finish.
I've seen this table in several places and I like Steve Bottorf, so I'm linking to his version:

Personally I think this chart is most useful for perhaps using it as a guide to how to blend a satin finish after you've used a certain belt. For example, if you finish with a 180 to 220 belt, the Medium Scotchbrite is probably the right match. If you finish with a 320, a VF is probably the best match. But I'm just guessing.
Check out this video which shows how Scotchbrite is used along with other abrasives.

Incredible result!
