Is spray foam or blown-in insulation better for an attic in Plainview?
For most attics, sealing the gaps and topping up with blown-in is the better buy, because foam costs more and the sealing does much of what foam would do. Foam on the roof deck usually wins when your ductwork runs through the attic, since it brings the ducts inside the insulated space. I'll tell you which one your attic calls for once I've been up there.
