JC, those with experience with these speakers will surely show up to offer their opinions, but in the end, your's is a question that nobody can answer but
you. There are so many variables involved: your taste in music; volume levels; preferred speaker characteristics (bass and treble output, midrange balance, and all those ethereal ideas such as staging, directionality, yadda, yadda). And we haven't even mentioned room characteristics or the gear you will be using upstream.
In short, this is going to be a matter of auditioning these speaks personally and choosing between them. But,
then you can take them home to your environment and gear and sit in amazement when they don't sound
at all the way they did in the store (they could sound better or worse

) - for all the reasons mentioned above and more!
So, start listening - and enjoying the process.
Oh, and make sure that your dealer has a
no questions asked return policy.
