I don't know much about either of them, however, as I found the last time I bought tires, and I will be buying again yet this year, as our bikes are getting older and fewer of them on the road there are fewer tire options to pick from(especially radials). I may end up back with bias ply this year.
Whatever you do end up buying, be sure to check/inspect the date stamp on the sidewall when you receive them. The last thing you want is a 2-3yr old "new" tire just because it sat on a warehouse shelf doesn't necessarily mean it's new.
