It's Garnet Valley's triple-option, run-heavy attack vs. Perkiomen Valley's spread, wide-open offense.
The contrast in styles will play out when the No. 10-seeded Jaguars visit the No. 3-seeded Vikings in a PIAA Class 6A first-round matchup at 7 p.m. Friday in Collegeville.
The contest also serves as a District 1 semifinal, with the winner taking on the Coatesville-North Penn survivor next weekend.
Garnet Valley, which is seeking its first district title since it won at the old Class 3A level in 2007, is fresh off a shocking 42-14 upset of No. 2 seed Neshaminy.

Garnet Valley racked up 300-plus rushing yards while passing only once against Neshaminy.
