What renders faster - sprites or models?

Question

Game development

There will be about 30 objects in the scene, low-poly, around 100 polygons, so how will it be more efficient to render a total of 3k polygons or replace these objects with just sprites (30 sprites)?
I would choose sprites myself, but the problem is that in total you will need 60 sprites (for two sides), there will be only one sprite in the frame at a time, and then doubts arose.

What is the target platform? Abstractly, in a vacuum, one quad is, of course, less than a hundred triangles, but the quad will be drawn with transparency, and maybe your specificity is such that you are more afraid of an overdraw from transparency than additional triangles. But generally speaking, only a profiler can answer such questions, make a test scene and see, guessing in such things is harmful. In the context of mobile phones, three thousand polygons is quite small, with proper batching and not very bold shaders, it will quickly be drawn. Maybe according to the test results it will turn out that you don’t need to pervert with sprites.
