Personally, for commercial use, I would always use OEM components and on any of my drones. That and good maintenance is the best insurance against a rapid, unplanned disassembly.
Prototyping and manufacturing technology is so advanced now, there is probably little to no difference between OEM and aftermarket parts. Unfortunately, given the long life of batteries and props, there is no reasonable way for the average person to do a scientific test and comparison between parts to know if the quality, durability, and life, is the same.
Since failure of either a prop or a battery would be catastrophic, the safest course for my company, with the data I have available to make the decision, is OEM. I see it as a risk limitation issue.
For personal use, experiment and have fun. I have a 10 year old home-built quad that is a Frankenstein’s monster of parts, and I have never had an issue with it. Just fly in a safe area.
Fly safe.
