I've used both CC and OpenCode quite a bit and while I like both and especially appreciate the work around OpenTUI, experience-wise I see almost no difference between the two. Maybe it's because my computer is fast and I use Ghostty, but I don't experience any flickering in CC. Testing now, I see typing is slightly less responsive in CC (very slightly: I never noticed until I was testing it on purpose).

We will see whether OpenCode's architecture lets them move faster while working on the desktop and TUI versions in parallel, but it's so early — you can't say that vision has been borne out yet.
