Best way of pool closing with what chemicals needed? Winterizing kit or Pool Magic

[phillipjko]

With Phos Free. Someone told me not to use those BS IntheSwim pool winterizing chemicals as the pool when open gets dirty.. which is true My pool has ALWAYS been dirty when I open it each year using any of those $49-64 winterizing kit even with the Pool Winterizing Ball which guarantees clean pool. So far all were BS. Will pool Magic do the trick??? I have a 22k inground vinyl pool.
