Django because I'm already good / fast at it. If you're already at that level with Rails, use Rails. One challenge of the Django approach today is deciding between a modern or "classic" front end. I think the answer is not black and white and really depends on the amount of interactivity in the app. I would not use Google Sheets as the backend for anything more than a side project based on performance issues mentioned by others who have done so. Still, I think it's a really cool idea. I've considered trying to write a (partial) Google Sheets backend for the Django ORM.
