rico soul: I posted a comparison the Point Factory and this TieChuang Exia frame in the PF listing so I figure I'll put it here as well for people that may be wondering. Unfortunately, it appears that this frame is out of stock on Gundamit now.
In short, you can't really go wrong with either one but for me, TieChuang wins out slightly as more of a re-engineered frame for the regular MG Exia, whereas Point Factory is more faithful to the original frame and so is more compatible with different kits and may offer slightly better value since the initial run includes the HGGTO RX-78-2 alloy frame as a free gift.
Ankle and Waist Joints:
- Point Factory takes the original Bandai frame and strengthens the joints by using tight POM parts to replace the original polycaps. It does not however, redesign the joints, so the double ball jointed ankle is still there. The improved frame stability is purely from better materials.
- TieChuang redesigned the waist and ankle to use peg joints rather than ball joints. With the outer armor on, the articulation is pretty much unaffected but the new joint design is just simpler and sturdier. However, the new design makes it not compatible with the original rear calf armor so new pieces are included in 3x colors for white, trans am, and astrea red.
- Conclusion: I believe TieChuang's change is better, but both are vastly improved over the original Bandai frame.
LED unit
- PF: The included magnetic switch LED light has an extra wire that will need to pass through the pre-drilled neck ball joint to light up the head. The LED light has several spinning patterns for the GN Drive.
- TC: Also a magnetic switch LED with similar flashing modes for the GN Drive. Head lighting is achieved by a light piping neck piece but effect is weak. However, since there's no wiring, it's a simpler installation with no risk of snapping the wirings when rotating the head too much.
- Conclusion: I slightly favor the point factory design. It's brighter lighting for the head and the neck is also alloy.
Aesthetics:
- PF: The design here treats many of the completely exposed frame parts as grey outer armor and uses POM parts rather than metal parts. So this means the part of the frame that sticks out of the knee armor, and the lower portion of the torso.
- TC: The torso is pretty much completely opposite of Point Factory where the exposed part is metal and the hidden parts are POM. The exposed knee armor part is metal. The back of the knee deviates from Bandai's design and has a visible POM part sandwiched between two meta parts rather than only the two metal parts snapping together.
- Conclusion: Personal preference but I prefer the TieChuang look. I like seeing more of the metal show through and the redesigned knee looks more symmetrical even though the POM part isn't necessarily prettier.
Other:
- PF: The knee and hip joints use a ratcheting mechanism. Total weight with everything is about 230g. The thigh frame is still only a partial frame like the original so it is still compatible with all original armor pieces. The polycap inside the thigh was replaced with a whole block of POM. There are more screws used in the PF frame to keep things nice and secure.
- TC: No racheting mechanisms so the joints are more just regular smooth feeling joints. Total weight is about 235g. The upper thigh frame is redesigned to be a complete frame which looks nice as a bare frame but doesn't really change anything when fully assembled. However, it means it requires new thigh armor as well which is included in the 3x colors for white, trans am, and astrea red.
Overall:
- PF: Despite a slightly higher price, the package can offer greater value because of the extra gifted HGGTO frame if you wanted that. Because there are no frame connection changes, there are no replacement armor pieces needed so it's fully compatible with any colored Exia or compatible model kit.
- TC: The TieChuang frame is imo better as a pure re-engineered Exia frame. However, the LED performance is weaker for the head, and while the modified ankles and thighs frames are great designs, requiring to use one of the 3x provided colors for replacement armor make things less color compatible with kits like the Dark Matter or special color or clear Exia kits.
