To me, it's that these apps are established and developed into a clean user experience, many with like a decade of fine tuning. These new apps are, to me, not as good for that reason alone.

Of course it's all preference, but that's my input on the subject.

I found boost a great app and I was one of the first people (if not the first, my post on his sub is the first instance of it) to tell Ruben to make a lemmy app. I like Ruben because every single time I've ever had an issue with Boost for reddit, he responded directly to me and either helped me solve a user error or he would literally patch the app and push an update that included my issue. He's a great dev and I'm glad he's decided to continue development else where, and I'm glad to support him in this. While I could easy patch ads out using lucky patcher, I will pay for premium of boost for lemmy as soon as it's ready
