East Coast US - Tire Choice

I'm racing my first season of XC this year. I'm in Pennsylvania so courses are typical rocky, rooty, twisty east coast singletrack. I have two options for tire choice (I already have these and so I'm not interest in other options.)

For those with experience what are your thoughts on the Vittoria Barzo/Mezcal combo vs Maxxis Aspen front and rear.

Thanks for your opinions and sharing your experience.
