It’s a bit confusing so bear with me. The exclusive seat that was fitted as standard on a GS triple black can be identified by the GS logo on seat highlighted with silver stitching. It was definitely comfier than your present seat. The latest comfort seat is comfier but is not the same as the one I’ve already mentioned. So to answer your question, yes I have the experience and the comfort seats are better BUT in my opinion not much better and not worth £350 plus. I find the standard seat on the GSA a literal PITA . I’ve had a gel pad fitted into it which helped a bit but am now going back to using an Airhawk seat pad.
