The new one :
The old one is clean and concise and not overly complicated.
You can browse through each topic easily because it doesn’t has lots of pointless white space and feature to distract your eye.
The old one can edit your post without time limit (15 mins for new one)
To make matter worse, the new one includes downvote feature, on top of being visible!
It can even generate in game conflict because people might whisper to the downvoter ingame for downvoting their post.
