Unknown 6.5-in Flat Black Pad

I was polishing today and noticed that one of my 6.5-in black flat pads is different from the other two. The foam on the lone pad is different (more open celled) and feels rougher.

I am sure two are Lake Country but not sure about the third. They all have the notched recessed velcro. I have a fourth pad, blac Meg's Soft Buff 2.0, which I thought was a Buff and Shine pad but the foam seems like the Lake Country.

Anyone have both a black Lake Country and black Buff and Shine, or black Uber pad? Which feels softer?
