The main thing that has prevented me from using Logseq is the general slugish or delayed feeling of the GUI. It's not significant but enough that after using it for 2 months I swapped back to org-mode in Emacs. Even though I love org mode for general project planning, task management (gtd) and such, I have never found a comfortable workflow for actually writing non-code/non-markup in Emacs. The logseq experience of writing notes was immediately comfortable for me. Just wish it was fast.
