Yeah. What they said.
Finding a dirt sound that you like is very personal. I like a lot of different dirt sounds when I hear other people use them but when I’m playing I get real picky about what I’m hearing.
I was talking to a guy a couple of weeks ago that, like @joeike, couldn’t find a sound he liked with a Tube Screamer and ended selling it and getting a Boss Distortion that he loved.
My son plays guitar and never liked the Big Muff sound. He swapped his Big Muff with a friend for a Tube Screamer and that never really felt right. Then, I went to visit with my Bass Tube Screamer and we stacked his Tube Screamer with my Bass Tube Screamer and his face lit up like he had just found what he had been searching for. It was beautifully nasty.
When it comes to dirt, first decide what level of dirt works for you. From least to most, there’s overdrive, distortion, and fuzz. There is a lot of cross over between pedals that call themselves one or the other.
Check out this video for a comparison of a bunch of different pedals.

Try not to think too hard on it. If one stands out that you like. Look it up for videos specific to that pedal. You may decide you just don’t like fuzz.
