I’m not familiar with those two… But I’ve always been hunting for the perfect replacement.

I started with Nextcloud Deck and used it extensively until they got rid of my markdown support.

So then I tried taiga and a few others before landing on Wekan. Really great software, but the terrible API, horrible mobile support, and slow outdated UI drove me away…

Now I’m on Vikunja, which ironically doesn’t support markdown text. So I basically returned to square 1 with a better UI lol. I almost stayed on Wekan because of the checklist support, but the faster speeds, nice API, and slick UI in vikunja landed me here… for now.
