I have one on my Speed Triple/Daytona (same tail/seats as yours)
I've done a 700 mile day & a 600 mile day on it & survived quite nicely!
I can't really compare to OEM as it was on the bike when I bought it.
I will say that I recently bought a new Corbin for the SV - the quality was disappointing - it was assembled incorrectly with the forward bracket mounted backwards; even when reversed it would not align with the frame mounting holes. I had to elongate the mounting hokes for bracket to seat, then grind away some material from the fiber-glass seat base in order to have the bracket mounted far enough backwards to fit. What was most shocking is that in two e-mails to politely point out the issues to their customer service, I received no response. In light if those experiences, I will never buy another Corbin product.
For my TL seat, I intend to send the OEM to Spencer at
Great Day to Ride - if you search across various motorcycle forums you will find countless testaments to what he does in reconstructing your stock seat for improved comfort. Even with the added Supracor option, you're still looking at way less than half of a Corbin investment.
(Note that he also has links to some custom replacement seat cover companies on the FAQ page, if you want that replaced at same time as the foam re-work)
