So if I have 100 sprites I should send 100 view model matrix with glUniformMatrix4fv and select them with gl_VertexID/4?

I didn't read into it the first time, but the answer is no. A big no. It's much better to use uniform buffers for something this big (or for something that you're going to share). In fact it's better to limit the usage of global uniforms only to those cases in which the overhead of using the buffer is greater.
