I feel like this might largely be a question of UI preference, as I haven't found something I did in BurpCE that I really can't do in ZAP, and I would say that ZAP is more intuitive. Also, the tabs in Burp are super annoying, and can get unmanageable when you start to have a ton. There are definitely some rough patches in ZAP where doing something looks to be possible, but its just easier in Burp. I do find myself in ZAP more than BurpCE after really getting used to ZAP.

That being said, it seems like Burp's paid feature set is much more of a "Web Application Scanner", which devs can leave running somewhere and just let it scan and flag stuff, as opposed to ZAP, being a tool for web app vuln testing that has to actively be used by the end user.
