Alto Utopia to Scala Utopia V1, worth the difference?

I have been in the market to upgrade my mains and push my current Focal 926s to the rear surround position.

There are a couple of threads in this forum that discuss the Alto Utopia Bes and the Scala Utopias, but I'm looking for some additional guidance.

I have found pairs of both and negotiated as much as I could...the difference in price for these speakers will be about $3500.  Are the differences between these speakers really enough to justify the price differential?

I do like the idea of having an adjustable crossover and having the newer improved drivers...however are the differences going to make sense $$$$ wise?  Would love some fresh prospective from some of my fellow hobbyists!

Thanks,
Ben
