I've never seen either up close, but I've heard the fit and finish of the Adreniline is top notch. They are full cap, and pretty blinged. I think they run pretty fast and can handle the rough. I'm assuming you saw the claims in the Adreniline section of running 90 in 6'ers? I'm sure that's far fetched but they appearantly will handle some seas for their size.
There's a place on the west coast trying to "give away" two of them. Like $160 with 700 and NXT and 180 with twin 525's, they run 92 and 97 respectively, and both are absolutely beautiful.

They seem like awesome deals compared to their MSRP.
I don't know the pricing on the SSR's, but they probably are a bit heavier on the amenities, and are bad ass as well. I don't know their speeds, but I think they're pretty efficient. From what I gather Sunsation's customer service will not be topped.
I'm sure there are people more qualified to answer this that have hopefully been in both. I don't think you could possibly go wrong with either.
For the money I LOVE the Adreneline with the 700 and NXT. I'd think it's pretty economical speed with the single and big drive.
