we're paying ReplIt $1500 now

In a lot of organizations, it is pretty easy to burn a significant multiple of $1500 switching systems you use 0% of because the business does not stick.

What I mean is the question reads (to me) as if the only motivations for switching are irritation with the marketing and not finding additional value in the new features.

That might not exhaust the list of actual problems, but those are the only ones I can suss from the question. If you were going to build rather than buy, maybe they might make a better business case. Good luck.
