If you're heavily invested in one, switching is a chore, though much of it can be done slowly, and with all of it integrating with Alexa and/or GH, the UI end of the automations can be slightly less painful.
Similar here. 50+ devices (switches/lights/sensors), hooks into Alexa, IFTTT, Stringify, and even some SmartThings stuff like our phones and TV, makes me hesitate a switch now but I would def go Hubitat given the feature set, community support, and adoption rate.
