Any particular reason you like Glasurit?

I had a pint of Glasurit 21 single stage urithane accrylic paint that came with my car from Reno NV.I have used it all and am having a time trying to find another brand to match my crystal white paint. I've tried Shermin-Williams and am on my thrid can and still no match. They seem gray in comparision.Everyone seems to be totally base coat -clear coat oriented.  I understan Glasurit now has #22.  .I've found a local supplier that sels to bodyshops but doesn't mix. The one local bodyshop  that uses Glasurit paint thatI talked to only does the base coat and clear.
Is base coat-clear that much easier to do, match,  repair,more durable than single stage? I've had great succes in repairing my crystal white single stage  urithane accrylic pant untill I ran out.using the dab and wet sand  then polish routine .No spray cappability.
