The first build never lasts long as there is always something that needs to be changed, added, or reversed.
Something simple like having your fans set to exhaust instead of intake can lead to having to re-bend half of your tubes, or not giving yourself enough space to properly run your cables. All things that can be avoided by going soft tubing.
Now, once you have a couple builds under your belt, you can properly plan a custom loop without any issues, that's when you go rigid.
Obviously that's just an opinion, but installing rigid tubing being more time consuming and difficult than soft tubing is a fact. I'm of the opinion that when you first start doing something, you should simplify it as much as possible and in this situation that would be soft tubing.
And yes, this it is for beginners. If you already have a custom loop, you already have a pump and/or rads, fans, fittings, tubing, blocks, etc. etc. so buying this kit is pointless.
edit: The tubing they are using is actually really good and none of the issues that come up with soft tubing will show up before the loop has been taken apart for adding more to it because, lets be honest, it's addictive. Anyone who gets this kit will be ordering GPU blocks, more rads, etc. etc. in a few months anyways.
