Does it make sense to develop a SaaS app in a saturated market?

I am working on a form-builder (SaaS) app. I have had this idea since 3 years, made some prototypes but stopped started on launching it until recently.

Today, a basic competition analysis shows that there are a lot of such form-builders available. And actually with more features than I can get develop in my first version.

USPs: Lower pricing (not too low) and couple of features that I personally wished these existing form-builders had. Maybe lower pricing is not much of an USP

Leads: I have zero-customers/leads at this point. I am still working on the landing pages and will be accepting registrations pretty soon via a few channels.

If it works out, my long term plan for this is to extend this into an app-builder and allow a smooth transition from plain form data to application-data-models.

What do you recommend? - Does it make sense to develop a SaaS app in a saturated market?
