i'd just rather use pycharm. https://www.jetbrains.com/pycharm/
My debugging now is just logging.info and some fancier log aggregation tools, but still feels like the early 1990s.
Whether "PyCharm has almost everything that Sublime has" is not really relevant to whether people claimed IDEs were bad -- seeing that people didn't claim IDEs were bad for lack of features.
It's the slugginess and especially the "take it or leave it" bundle of stuff that comes built-in into an IDE that annoy(ed)s people.
Also, I'd argue PyCharm has much more than sublime.
The rest of the list is pretty short: Plex and 1Password (less so these days).
That being said I think PyCharm is good enough that I'm willing to put up with that.
