Pretty hard to advise on buying speakers without you auditioning them, and if you can audition them, you won't need anyone's advice.
Having said that, I was never a huge fan of the Watt/Puppy in early iterations and haven't heard the 8s so can't help there, Have listened to Sophia 3 and liked them a lot. I personally have older larger Wilsons and would never give them up (I also have other very good and very different speakers in other systems).
With Wilson, you pay more, but you generally get quality stuff. OTOH, you might want to add the Vandersteen 5A to your list....
