You might be thinking of someone else. There are people out there with a menagerie of totally different props (slow-fly, eprops, gemfans, triblades, balsa wood, glass fiber, carbon fiber, you name it).
I've got 16 pairs of various Phantom-style props (8" 8045 DJI, 8 inch carbon fiber knockoffs, 9" 9443 dji self-tightening, 9" dji non-self tightening, 9" carbon fiber knockoffs, etc.). Never tried the Tiger motors ones; they look nice buy super-expensive, and I wouldn't want to crash them.
IMO the 9443 props are the best bang for the buck you can get. 20% flight time increase over stock Phantom props. The genuine DJI ones have the benefits of being 1) fairly inexpensive ($30 for a set) and 2) pre-balanced at the factory. I have those on my new multi. My Phantom 1 lives on carbon fiber knockoff 9443s. Any knockoff props you buy will need balancing, the clones are not as good on manufacturing as DJI is. I don't mind doing the work of balancing, but a lot of people don't want to bother with it, and that's what makes the genuine ones so advantageous. I haven't noticed any actual difference between a well-balanced set of carbon fiber 9443s and the genuine DJI ones. The carbon fiber ones are lighter by about 2g per prop.
