Hmm... these have been well hashed out in two main threads. All you need to know is in 'em.
I am quite happy with my Sargent. It's a pretty radical departure from stock, design-wise, and that doesn't sit well with some folks, but it's okay by me. You'll note from the above that a lot of people don't like the fit of the Sargent, saying it leaves a gap by the side panels. On my bike, the gap is there with the stock seat too, and unless they're lookin' for it, nobody's gonna notice. It drives other folks nuts.
Both companies offer customization and money back if not satisfied, so try 'em and see what suits ya.
Here's mine, low angle so you can see The Gap. I have photos of the stocker too - it also exhibits the same Gap:
"I hate to advocate drugs, alcohol, violence, or insanity to anyone, but they've always worked for me."
