Low Poly Alpha Cutout vs Full Models Performance

Hi, Quick question for those familiar with shaders and performance cost. What would be better for performance for small scatter objects like leaves & sticks? 1- Low poly(2-8 tris) planes using alpha cutout shaders 2- Still low poly but higher(24-36 tris) full models using a standard lit non-alpha shader Mentioned above but would be for lots of scatter pieces/piles through the scene covering most of the grounds. Thanks for any assistance!
