Old reddit gives far more information about each submission on the page and is lighting fast. Nu-reddit wants to be an instagram style mobile first feed app and you can only see one submission at a time. Clicking on the comments is maddening because it doesn't even show all the comments before ending and suggesting other posts from the subreddit. If I wanted to see them then I would click on the subreddit hyperlink. Additionally it only shows the first node of depth for each op content so I can't follow the conversation without clicking again.
