I am on both. Here's how it looks:
Open here, find an actual thread about something, people replied, conversation happening, I even contribute. Check more — oh look, another good thread I am interested in — read, learn new stuff. Feels a little bit slow. Let's see Soyjak!
I open it. Loading… loading… oh, they got hacked… it loads — oh, okay, it's just flooded.
Instantly, I wince from several epilepsy-inducing gifs. Okay, what's else in the catalog? Scroll past 10 same threads about "reee 4chan here," a few threads "4chan here suck my 4chan dick reee," finally see one — oh, Iran did what? Open it. Huge asshole is the first 5 posts, then Iceland won, then someone commented on Iran and was ignored… okay, this place is shit, see a few nasty gifs over there, and come back here.
