If I were choosing between those two I would go with Obsession in a heartbeat...
@Markus Luukko installed one of these kits not too long ago.

The main reason is because of the way the oil return line is designed. Other than that it is a toss up between the two and personal preference.
I have been told by at least two people I trust that the Irate kit is good, but the oil return line is a major pain in the ***.

The performance of the various kits is going to be nearly identical as it is just plumbing, a plate, nuts and bolts. Take a look at the Irate kit oil return line and how it goes into a freeze plug in the valley.
I don't know about you, but I was not interested in putting another hole into the valley of my engine. The two people I trust that have installed the kit say it was good, but getting the oil return line right was a pain in the ***.
The Obsession kit, just like the CSD kit use the factory oil supply and return ports. That may not be important to everyone, but it was for me.
Again, performance is gained (or lost) in the turbo, not the pipes and clamps that are attached to it.

Maybe go to the FTE chapter sub-forum and ask for a trusted shop.
Quality of work is more important than price in my opinion.

The freeze plug is no big deal, but fitment of the return oil hard line is a pita. I will likely have a hose made for this if I have mine out for some reason.

You will be pleased with the kit and definitely have to give us updates when you stop smiling and laughing at how well the engine runs.
