They're really nice! They don't have Ektar pushed; did you mean Portra pushed? That pack is definitely my favorite. The original Portra is really nice too, but it is a lot more subtle than the pushed pack.
That being said, I prefer Replichrome. It has all of the Portra films and Ektar films, and you have the option of Frontier or Noritsu. It also has the option of over exposed or underexposed for the film presets. Pack 1 contains Portra and Ektar, Fujicolor pro films, Tri-x, TMAX 3200, Plus-X, and Kodak BW 400CN. You get all of those for the same price as one Mastin pack so I would say it's a better deal.
