I posted in the ST forum that achieving a stable configuration of plugins in ST4 seems more difficult than it should be, but they declined to take this on as a problem.
Meanwhile Zed made it pretty easy to achieve a stable set of plugins very quickly, particularly around language services, shell integration, etc. That's what prompted me to switch; however Zed has taken a few steps backwards in that department since they started spinning out language extensions into plugins that require more configuration and are more prone to breaking.
