I believe it's a debate here between ZT and the Pohl Force.
Some people like the G10 (Micarta) handles on ZT, some like the zytel on Pohl Force. Let's see the difference between those two:
G10 laminate grades are produced by inserting continuous glass woven fabric impregnated with an epoxy resin binder while forming the sheet under high pressure.
"This material is used extensively in the electronics industry because its water absorption is extremely minimal and the G10 line of materials is not electrically conductive. The G10 is most commonly used in PCB (Printed Circuit Boards) applications. G10 exhibits superior mechanical and dimensional stability and doesn't shrink. Temperature ratings of 180 degrees C. In addition to these properties, G10 has excellent dielectric loss properties, and great electrical strength. G10 is also known as Micarta and Garolite and can be used for structural supports, buss bars, mechanical insulation, gears, test fixtures, washers, spacers and tight tolerance machined parts for electromechanical assemblies."
Micarta can be made from paper, linen, or canvas. The paper micarta has almost no grain, linen micarta has a little and can still be fairly smooth when polished, canvas micarta usually has a little roughness even when polished, but is normally not polished and left rough for more friction.
"One of the top materials for knife handles is Zytel, a product made by Dupont. The technical description from Dupont says Zytel "is a nylon polymer family that offers a range of expertly designed products to help components deliver as designed in harsh environments resisting aggressive chemicals, flame, heat, cold and even wet, humid conditions."
Less commercially described, Zytel is a nylon material often reinforced with fiberglass for additional toughness and resistance to solvents. It holds up well in extreme conditions and is extremely tough and resists corrosion. It can survive for long periods in salt-water conditions which makes it a good choice for knife handles used by the Navy SEALs. Another feature important to the SEALs is that it does not become slippery when wet.
Zytel knives have been created for the Central Intelligence Agency for covert military operations and continue to be used by various agencies for covert (black) ops. In addition to the SEALs, Zytel knives are also used by the Green Berets.
Zytel is extremely popular for knife handles, including knives made by Gerber, Benchmade and SOG, because it is extremely light-weight; it weighs less than one-fourth as much as steel. Other reasons Zytel is one of the most popular materials for knife handles are that it doesn't expand or contract in heat or cold, and it won't become scratched or discolored with heavy use. Zytel naturally has a slightly textured surface, but knife companies will usually add more texture to help gripping and holding.
For manufacturers, Zytel is popular because it can be injection molded which helps keep costs down even though it is more expensive than some other materials. It is also available in many different grades.
It's little wonder Zytel was chosen for the handles of the SOG SEAL Knife and the SEAL Pup. It was created for both strength and durability. It has proven to be both durable and maintenance free, and it definitely makes a knife more affordable. Because of its many features and affordability, it is likely to reaming a very popular material for knife handles for both every-day users and well as Navy SEALs and other special forces for years to come".
Liam Conley, a 15-year Air Force veteran and intelligence analyst has been a knife fan and collector for years. He thinks that if you want to find a high quality knife, you learn what knives are used by people whose lives depend on their knife. Then you determine why they use those knives and what sets them apart.

Now let's see the steel inside both folders:
CPM S30V
The newest stainless steel from Crucible, purpose-designed as a cutlery steel. This steel gives A2-class toughness and almost-S90V class wear resistance, at reasonable hardness (~59-60 Rc). This mix of attributes is making S30V one of the hottest stainless steels going, with makes such as Chris Reeve switching from BG-42 to S30V. Will this be the new king of general-purpose stainless cutlery steels? We'll know over the next couple of years.
D2 (What? indeed the newest Pohl Force Alpha Survival and other types use this kind of steel)
D2 is sometimes called a "semi-stainless". It has a fairly high chrome content (12%), but not high enough to classify it as stainless. It is more stain resistant than the carbon steels mentioned above, however. It has excellent wear resistance. D2 is much tougher than the premium stainless steels like ATS-34. The combination of great wear resistance, almost-stainless, and good toughness make it a great choice for a number of knife styles. Bob Dozier is one maker who uses D2. Benchmade has begun using D2 in its Axis AFCK.
I don't want to mention here the look of those two. (the bulkier ZT and the
way too fancy PForce)
That was my 2cents thought and I hope it wasn't boring
