I will admit that I am ignorant, so educate me. What is trail? What part of the front end trails and what leads?
If I I look at two bikes, one with a fork that is almost straight and a second with the old school curve, which one is low trail?
A straight fork to my mind will be twitchy, and a long curved one "slower" steering.
Google has many fine illustrations of trail.
Fork curve is not rake. You can have a curved fork with no rake and a straight blade for with lots of rake. Rake or offset is the amount of change from the steering centerline. Again, google.
Forks don't, on their own, do anything for handling.
