There are no questions about it. As an installer my advice would be constant force. Here are several reasons.

1) spiral balance must be adjusted and greased perodicly . (evry year is the advice given by Remodeling magazine.)

2) Spiral balance wear out 3 times as fast, and are never covered over 10 years by the manufacture

3) Spiral balance easily pop out of place when window is tilted in, and are very hard to get back into place.
