@LanGonCer9807 - You asked so I shall answer...
All three mods are attempting to solve some sort of single graphical/imagery problem. None of which I'd really think are problems. Therefore as I said, I don't see how they are solving a problem I've ever personally had before.
However, I see the realism/full makeover mods and it does make me think "hmm, yeah, I might give that a try if it enhances my whole experience". I think someone else has already mentioned above actually, perhaps all three bundled together will be more appealing?
