Prefer the devil you know to the angel you don't? ;D
Theoretically there's no real difference in how Drupal and Wordpress operate, they're both base things, and you add in modules/plugins to make the site do what you want and buy/make a theme to go on top right? Is that roughly how we see condenser working as well? Just so we're in the same sector of the universe?
I (perhaps foolishly) assumed the above so was focusing more on module management/development, and tldr I like how Drupal handle things more than what I remember of Wordpress is all, reasons below otherwise skip to next comment :)
What I remember of Wordpress was that trying to find plugins was a nightmarish mess, and there were a billion plugins that did the same thing. So for example if you decided you wanted to build a video sharing site, after you got your Wordpress installed you then had to try to work out which one of the thousands of available plugins would a) work best for you and b) not be malware. I'm assuming stuff has changed by now because it's been over a decade a decade since I last used it (fek I'm old).
With Drupal, they prefer people collaborate on one brilliant module than have several half-arse ones littering the place, so if there was a module that already did a thing that you wanted and you were writing one, you had to explain why your module was different enough from the existing one to be included and why it couldn't exist as a submodule of the existing one. So back to our hypothetical video sharing site, what you would do in this case is find and install the video module and any submodules/recommended modules (players and whatnot) that augment it. That's not to say that you couldn't just build your own thing out anyway and make it available, if the cms recognises something as a module it will use it, it just wouldn't be on the Drupal main site where most people go look.
Drupal also has a security advisory which I highly valued (modules have a red shield if they haven't been checked, yellow if there's a problem and green if it's been checked and found all right, doesn't stop you from using it if you want, it's there for informational purposes) but I don't know how practical that would be for here and either way that's a much further down the line thing (as I don't recall the security advisory being a thing til Drupal 6 or 7, though that's also when I subbed to that mailing list so it's entirely possible it existed at some point beforehand).
Only vaguely related, video is also a nightmarish pain XD
