Pla and petg are two different materials, each with pros and cons. Pla is super easy to print with and smells nice, but it can be kinda brittle and relatively weak (if printed properly it can be pretty damn strong). Petg is harder to print, but it's stronger, a bit more flexible, and can be pretty translucent. Pla is probably a better choice for most applications, especially for a newer user, but petg has its place.

I’m decent at 3D printing and I have a printer that can handle petg. So you think that pla is best for me? Thanks

It really depends. But generally, I would say yes. Unless you absolutely need something that can take more structural load and flex before breaking. Pla can print faster and easier. It's the move for general printing.

This. I use PETG when I have to print parts that will be subjected to pressure, like e.g. I had to print a cover for the drainage-hole in the garage and I knew that there's a good chance people will occasionally step on it, so it needs to withstand flexing and still be strong. PLA would've cracked in no time, but PETG doesn't mind even my fat ass stepping on it. PLA I use for e.g. printing cases for electronics, small fixtures for stuff and generally things where precision matters more.
