This is one of the most subjective buys for a bike (simply because everyone's got a different ass). So, take this with a grain of salt:
I had a Corbin two bikes ago, on an FZ6. It was a plank. If you like hard seats, go with the Corbin. I wasn't impressed.
I put a Sargent on my last bike, a V-Strom.... fell in love with it. It had its own storage underneath, and was actually comfortable as hell.
Soooo... I put a Sargent on my current V650 2015. Love it. It's the standard version, because I'd rather lower the bike, than the seat (that way the leg geometry and ergos remain the same). It does away w/ tank crunch due to forward lean of the stock seat, and it wears like iron (its not leather, but, I prefer non-leather, due to better weather resistance).
The V650 Sargent doesn't have the room for the storage underneath, like the Strom's Sargent, however, it's a solid baseplate, and very well constructed. I'll be happy to post pics, if you like.
