ATC SCM19 Speaker vs. Kudos Super 20

This probably sounds a bit of a wimpish question but I'm going to ask it anyway. We're in the closing stages of deciding on which new speaker to replace our faithful early and still good sounding, Linn Keilidh speakers on the end of a new 272 + 250DR combo.

The new speaker selection criteria are acoustics, aesthetics and some specific size considerations, plus as a secondary consideration the cost. After evaluating a lot of candidates it's come down to two rather different solutions. Either Kudos Super 20 or ATC SCM19. I've read everything I can find on this Forum and elsewhere on the Internet plus home auditioned the Kudos Super 20 which we like but not home auditioned the SCM19 which we've only heard in a dealer showroom. However, I (not we on this point) can't help wondering if/we should home audition the ATC SCM19.

I know that the proper answer is to try it for ourselves at home but don't want to waste anyone's time or end up driving approx 250 miles total just to try the SCM19 if there's an 80% agreement on collective forum wisdom that's already available. 

The room is a tad acoustically bright, measuring 12' x 25' with 7'6" ceilings - open at one end through an archway into another room and at the other end an open stairway. Speakers need to be wall friendly at the rear as they must to sit close to the front wall - they fire across the narrow room dimension.

The Super 20 is not the cheapest solution at approx twice the cost of an SCM19 but for our ears, it does everything well albeit possibly a bit bright but then that's maybe not surprising after living with the early Keilidh speakers for a couple of decades. I'd only want to home audition the SCM19 if there was a good reason. I should mention that the SCM19 gets a demerit point due to WAF although that's negotiable  

Any thoughts on if a SCM19 home audition is a 'must do' or little to be gained please? As mentioned I know the purist answer but if others have already trodden this path ...
