Doughboy Desert Spring 16ft round or Sharkline Matrix 15ft round?

Hi... I am trying to decide between these 2 pools... The Doughboy is a little over $900 dollars more.

The Sharkline pkg has a 1.5 Hayward sand filter (115 V)
The Doughboy pkg has 1. Hayward sand filter (220 V)

Everything else in the package is comparable....

Any input woud be greatly appreciated! Thanks....

How big is the filter? What kind of pump? Are the materials the pools are made of the same?
