Experience with vinyl selection?

We are looking at replacing our vinyl, and the guy dropped off the vinyl options we can choose from. I ave a couple of questions if anyone has gone through it already:

1) With a dog and kids, does anyone have opinions on the weight or abrasion more important.
2) We have seen 30k Wyzenbeek, 1.2Million Wyzenbeek, Double Wyzenbeek.. any suggestions?
3) Does anyone have experience with:

A) Mobern Marine Mellohide (wave or shock)
B) Keyston Olympus
C) Keyston Softside


Thanks in advance?
