I needed a new windshield a couple of years ago for my 02 Camry. I called my local PPG installer (found them via PPG's website). To my dismay they showed up at my door with a piece of FYG. It was going to take another week to order a PPG, and I would not have a second vehicle for the following week (I intended to park it for 2 days to let the glue cure), so I accepted the FYG. Optically it was as good as OEM (I think it was an AP Tech), the tint is a little darker. It took a few rocks and got chipped at a few places since, but no crack. Over all I am quite happy with it.
FYG seems to be the OEM for GM/Toyota/Honda in China. According to this article I found, it seems to hold up well against rocks (at least for the one application they tested).

I studied FYG and other Chinese companies' glass. True, they are OEM for China market cars, but the glass is not even close to what is sold in NA, Europe, or Japan. It is thinner - less chassis rigidity and less airbag holding capability (airbag blows off of the flex of a broken windshield).
This article is interesting, but does not prove much. i.e. any film added to a windshield will improve its crack resistance, since crack tend to orginiate from the edges more than from the center. The results without the film added will be different by brand, not the same brand will score best. these films are not used for a variety of reasons: less breakage = less business for installers, they can delaminate and create optical issues, and are hard to apply.
The fit is a whole other topic. Some cars they get right, others no even close.
Most anyone in the world can make a good US GM A-body (Ciera/Century/Celebrity/6000) windshield or a 1st gen S-10/Sonoma/Blazer/Jimmy, because they are easy to shape and bend.
Most cars today are much larger and curvier - which requires proper forming to make sure they fit and not have optical distortion.
Using the right materials with a qualified installer matters most. Where it is done (shop or mobile) is irrelevant, if they know what they are doing and using the proper techniques and materials. the car shouldn't be driven anyway for at least 2 hours.
Rust on the frame is simply a function of putting frame primer on a cleaned surface before the adhesive and the problem is gone. Not doing this creates a rust problem when there may have not been one.
Still odd that the Mazda3 has Sekurit/Saint Gobain windshield, since they used to use Central Glass of Japan windows in a lot of their Japan made cars. Sekurit has to be imported.
