I have been to both and recently. If you just want variety I would say the Cocal in Jaco has a bigger variety than Habaneros in Panama City. The pricing will be higher on average $150 in Panama at Habaneros and $200 at the Cocal in Jaco.
Having said that read my thoughts on extra curricular activities. Jaco is better for that than Panama City. I like both and enjoy both so it depends on what your priorities are. Part of mine is to see and experience new places. I would absolutely recommend a day in Old Town if you go to Panama City. In addition you can fine a lot of high quality women in Panama City on this site
https://www.panescorts.com/prepagos/panama or this site. I have not had much luck on the 2nd one yet but there is choice.

Here is a tip for online stuff. I tell them up front that will require a 15 second video with them doing something specific like hold up 2 fingers on their left hand to show that the pictures are current and of them. If they refuse to provide skip them and go to the next one. I did not have any problem with finding good ones in Panama City that were open to send the video.
Good luck.
