I've been jumping around trying 4-5 clients since the Reddit Exodus and all of them had some really anything bug.
Voyager is the one that in my opinion is the best one feature and stability wise.
However, voyager if giving me one big headache in the form of going totally black if I swap over to fx read an email. I don't care if you're my Firefox needing things up. I'm not going to opt in even more in Google Surveillance just because Voyager is open source.
Sync for Reddit was my whole Reddit experience for the last 7-8 years. I think I tried a majority of the clients and Sync totally wiped the floor with the other clients in my opinion. Both in new features and stability.
I use Windows and several dists on a daily basis. I have an Android phone and I truly like the philosophy behind open source... With that said.... Competition is great. We'll see what Sync for Lemmy can bring to the table.
If it is as good as sync for Reddit was the other clients have to shape up and it's us, the users, that will benefit.
