Uponor, Thermotech or Purmo

Planning to purchase chipboard and sheets for our extension

I've looked at Uponor, Thermotech, and Purmo 17mm products, and there's quite a price difference between them.

Is there any reason not to choose Purmo (which is clearly the cheapest) when it comes to chipboards and sheets? Or rather, has anyone had a bad experience with them?

It shouldn't be a problem to use Uponor's pipes in the other suppliers' boards and sheets, right?
I figure it's most important that the pipes themselves are of the highest quality, so it's unwise to gamble on a budget brand.

As long as they fit in the tracks with the plates and everything that's supposed to be there, it doesn't matter, chip is chip, no difference, but they should be tongued and grooved so they lie still and evenly.
