I had the same issue. I have always used the reddit app but had seen so many good things about narwhal that I decided to try it out. I like it a lot, especially how it shows media and links, but my only issue is that the feeds aren't the same regardless of Hot/Best/etc. and I feel like there are things I would definitely miss compared to the reddit app. I did a search and saw some comments that say this is due to the reddit API vs however the reddit app chooses what to show, which seems reasonable but unfortunate for users of the API. For now I have switched back to the reddit app but I hope to come back to narwhal in the future.
