I just use old.reddit.com on my mobile and laptop.

Try i.reddit.com on mobile, it's easier on small screens. Click the cog on the right for options like collapsing comments.

Try teddit.net. It's not perfect, but mostly works fine. There are extensions that will replace reddit.com by teddit.net in the URL to make it even easier.
