Yeah Colon, was not the nicest part. My dad lives in Panama City, but when I visited I had to include a cruise on Pulmantur which did r/t Colon, the area around the port when I was there in 2018 was very under construction, but they must have finished it as RCL had stopped sailings from there at the time. Panama City, beautiful and felt very friendly, the little I saw of Colon felt very congested and less “pretty” ( these statements are 6 years old, areas can change a lot in that time, I am aware, but my dad would say the same thing and he relocated to Panama several years before that!)
