Do you have a photo of the bottom side of the tips? I can't tell if those are the kind used on the ATE that are coreless, and are made of gel foam. That type splits easily (because there's no rubber sleeve/core), are hard as a rock, and just flat out suck in general.
Anyways, as far as genuine vs generics (ball type and tapered type), I have both as well as all colors of the generics (white, grey, black, blue, red, yellow). Just get what color you like best. There is a very slight difference in the rebound of some colors of the foam, but not enough to make any real difference. If the seller specifically lists slow rebound as an option, opt for that. Otherwise, don't worry about it too much.
I personally like using red & blue combo, so it's easy to tell which side is R and L. But I've also done plenty of black. The white seems to show dirt the most. I also like the ball type a little better, but I use both the balls and the tapered type
I much prefer the generic foams over the genuine complys, strictly from a long-term cost standpoint. Foams need to be changed out regularly, and if I was using only genuine complys it would be like this:
