Same. The thing lacking is user base and content. Also a backlog of older content as knowledge source, but that would come overtime with through the former.
As far as usability goes Iemmy is just as good as reddit was for me. My instance (lemme.ee) is stable and the app experience (currently “connect”) is just as smooth as it was for reddit (where I used “relay”).
I sadly have to admit that I don’t contribute enough in terms of creating and posting threads.
Just to throw another option into the mix:
Maybe create a VPN connection with wireguard, then you can just transfer them however you’d do it in a local network? Tailscale would be an easy solution to achieve this.
