I can tell you my personal experience with this.

•there’s a lot of content on the surface, but most of it comes from automated accounts and reposts. Posting anything on any subreddit is increasingly hard. Mods and users do what they can

•the anti spam automated system is off the roof, you can easily trigger that with a new account, and both mods and users can fall victim of that.

•the recommendation system is liquid filth. You touch a post once, now you’re getting flooded with content from that subreddit. You can turn off the recommendation system deep in the settings, certainly not in a user friendly context.

•notification galore: even if you turn off those recommended posts, those can be notified by the app (or via email) at any given time. So I accidentally interacted with some awful subreddit, now I’m getting said subreddit notified at 4 am. Not even kidding here. Not even tiktok dared to send me as much notifications as the reddit app/website.

•lots of hate speech. If you leave the good subs, you can find openly racist posts (muted shitpotlicssay after n-word posting, both in the title and in the comments) and extremism in general.

Unfortunately it’s still a useful resource for technical subs, which are still good, but reddit as a whole is fvched beyond belief.
