Finally moved to my own place, with my own kitchen and I'm looking to expand my cookware now

Previously using only a non stick pan for most of my cooking, now I'm planning to get a cast iron, and currently deciding another pan between stainless steel or carbon steel

Which of the 2 should I get if I were to choose only one?

Will be used on gas stove fyi
so far what I've studied

Stainless steel cons
- guaranteed to stick without enough oil and a pain to clean
Carbon steel cons
- need to season before using (same as cast iron)
- cannot cook acidic foods like tomato, lemon or vinegar
