Generally better, but it's contextual. Someone saying with a surprised tone "It was pretty good" implies that it's better than good and better than expected, and that the person might not have expected it to be good. Someone saying with a muted or dull "It was good..." would be worse than "pretty good" and implies that it was acceptable but disappointing or mediocre.
I think for me it's generally the same but I'm not a native English speaker so idk lol
"Hey that was actually a pretty good performance for a beginner!" vs. "Well that was also pretty good..."
