Keyboard and mouse input for the phone is a gamechanger for me. Having a manipulatable window that I can drag and drop files to is super nice as well.
Also since Slay the Spire doesn't have cross-saving and all my progress is on my phone I can play it without staring at my phone.
At this point I'd nearly appreciate the removal of old.reddit or RES. My desktop browsing experience hasn't changed in roughly a decade and a half and that's a shitload of inertia. A few trims of my subscribed list has limited my exposure to the worst of the slop and botting.
Mobile is absolutely a different situation for both Reddit and Lemmy alike. I found Jerboa shortly after the API disaster and have stuck with it since, but I probably need to look into tweaks for desktop/browser Lemmy. RES and old.reddit are a killer combo but fuck their 'official' app and the 'new' interface.
Regardless, I no longer participate on Reddit and highly prefer interacting here; more interesting and informative conversations by far.
