Falken VS Silverstone

Okay, so Michelins and Pirellis are the best.
However, such imports to Thailand are not financially viable.
Given that Silverstone tyres are made in neighbouring Malaysia, they're the
most economical.
All the 4wd cars competing in the national rally championship uses them.
Now, prices aside, how would Falkens fare against Silverstones?
Gravel specs only.
Opinions welcome :-)
