It depends on what makes you "not super happy", but as someone who uses Dynalist all the time for everything, I must say the only reason I haven't switched to Notion is that their free plan has a hard limit of 1000 "blocks" (vs. unlimited in Dynalist). I actually haven't used it that much, but Dynalist doesn't have many features so it's easy to compare them and come to a conclusion.
From what I've seen, there are only two things I still prefer Dynalist for: Zooming into nodes (minor issue, since in Notion you can quickly turn a node into a page and "zoom into" it) and contextual search (major one, global search is a real pain if you have lots of data - but you can still make up for it by being more organized than I am).
As for everything else, Notion is a clear winner to me.
