No Plots definitely doesn’t do everything. Personally, I’ve found Plots to be the perfect plotting package for exploration. That is, to quickly look at things while I’m doing research, e.g., in a Jupyter Notebook. The package syntax is just very short and flexible. The multiple backends also come in handy. One of my favorites is UnicodePlots, which I love to use as part of running package tests in the terminal (but then switch to a different backend if I really need to see details).
However, Plots is not very good when you need extreme customization, most likely for generating plots for published papers. Personally, I’m still finding Python’s matplotlib unsurpassed, although Makie looks interesting if you’re looking for something in pure Julia.
