I'm mostly using Lemmy, but I still use reddit for some things where the lemmy communities are too small (like live sports discussion). If I'm googling for an answer to something I'll still include 'reddit' in the search because there is a huge wealth of info in past reddit threads.
Same here, missing communities like Cricket and PrintSF, so have to go to reddit for those. Trying to make it a habit to visit Lemmy first though, so every reddit pageview is preceded by a lemmy one
