Different materials have different properties, thus there is no "right" material for everything. I have used so far ABS, ASA, Nylon, PETG, PETT, Amphora, and TPE. And for prototyping, I always use PLA.

For example PETG is good for lots of things, but not super strong.
Nylon is slippery and wear resistant, but is slightly flexible. Amphora (HT) can withstand high temperatures and is very strong, but very difficult to print. ABS and ASA are great for parts that need further sanding and drilling. Etc.

If your printer doesn't have a heated chamber, you are probably going to use PLA and PETG exclusively, as most of the engineering materials require >60C chamber temperature, and nozzle temps up to 300C.
