With some people, when something breaks on their bike, they order the ideal parts online, and wait 2 months to get it. I like to fix my bike as quickly as possible, so I can ride it again. So I look for what I can buy here and now. If all I can find is plastic pedals, that is what I buy. I mentioned above that there are some nice aluminum pedals in a shop, but they are very thin, which suggests the axle is thin, and maybe not very strong. Maybe the axle is made of harder steel, and the pedals will last a long time. Plastic pedals are a lot cheaper, so I tried them first.
I do some riding on rough tracks. There have been times when pedals have hit rocks. If a cheap pedal gets smashed on a rock, it is not expensive to replace.
I am getting fitter, and riding longer distances. So bike parts are wearing out quicker.
I am larger than many cyclists. Some of the parts I have broken, would not break with a smaller rider.
I am also going through a learning curve. A few years ago, bike parts did not break like they do now. I am learning what parts are tough, and what parts break quickly. Certain things I wont buy again.

They may have different size teeth used as shift points that may appear to look bad to a non mechanic unfamiliar to parts design.
My old chain ring did have teeth broken off or worn off.
They do make plastic cranks. Maybe you would call it resin or something else. They have a thin piece of steel up the middle. Very thin. The steel in the middle acts in tension, and the plastic acts in compression.

I have had poor quality parts with Shimano written clearly on them, and now this with Avanti written clearly on it. I can't say for sure these are not fake parts, and have just written the Shimano or Avanti name on them. There are definitely some fake parts being made and sold.
I have not taken photos yet, and I am not sure it is important. It would show how thin the steel is in the middle of the plastic crank, which would shock a lot of people. If people just don't buy plastic cranks, problem solved.
