I have both , a SOG Flash II with the solid aluminum handle and a Spec/Speed bump with the Scandvik blade / G10.
They are both different and have their pros and cons, the SOG is a little less obtrusive in the pocket and feels more compact. The A/O works well, the safety is nice but a pain to switch on or off, the lock is secure. The pocket clip allows for low pocket carry and can be switched right or left but only the butt end.
Fit and finish is excellent and I'm pleased with it , the average price for one in this configuration is about $80.00.
The Spec/Speed bump is a real bargain at about $60 - 65 it is a limited run in this configuration. It is just a tad heavier and a little bulkier in the pocket but has a blade suited for more uses. The clip can not be moved and is tip down only. The flipper makes it easy to deploy, my knife is a little sluggish as compared to the SOG. The stud lock works well and while some hate it I'm OK with it.
I hopes this helps
