My personal vote is neither (tho you probably made a purchase by now)...there are too many other options that push up the performance and value factor.
The steels used are generally unimpressive with heat treatments that are not all that great, using many grinds such as the tanto with minimal usefulness for general usage, and with edge geometries that, in most cases, just aren't very good relative to the competition. Their budget knives often have locks which are strong, but also that tend to develop blade play over time as components wear...many of which are not user-adjustable. Like many modern makers, both companies have gone in the "tactical" direction by making things such as "world's strongest lock" or "a blade that can piece a car hood" or "a blade so thick it's shaped like a chode" and they have advertised using that base...the trade off is that it often results in a knife that is terrible for normal EDC cutting usage, and a knife that is bulkier, heavier, and less nimble. Almost all modern folders from good makers have locks that are more than capable for any work the folding knife will see...when makers get too caught up in the lock strength wars, they overlook more important aspects like blade geometry, ergonomics, or practicality.
Both makers do have some nice lines...but they are quite expensive compared to other options. Spyderco makes a knife family that in a value vs performance sense, it is incredibly difficult to find such a nice knife for so little money: that is the Delica and Endura family. An [Emerson patented] waved Spyderco Delica or Endura is far faster than any automatic or assisted...plus it uses VG-10 stainless which is an excellent steel, with a good heat treatment, with a robust sabre ground blade (which =s a very strong edge), and fantastic edge geometry...at a price that is significantly less than many of the SOG and Cold Steel folders made to compete in that class.
The Kershaw Thermite is an extremely inexpensive knife, but is assisted, uses a frame lock and G10 (premium components), has a reasonably good grind, and is in pretty good steel...all for under $30.
But if you are left-handed, the Spyderco Delica/Endura or Benchmade AXIS are arguably your best bets.
