I have been to Scotland twice and played Kingsbarns my second trip and really enjoyed it. It isn't a true links and the locals don't really think as highly of it because of this, the price tag, too much dirt moved, American architect perhaps I don't know. It was fabulous IMO for what it is (not a links), but when you compare it against 180 pounds for TOC to 273 pounds to Kingsbarns I would play TOC again before Kingsbarns for sure.
I played North Berwick for my first and only time on that same trip and enjoyed it more than Kingsbarns, because it was history brought to life. I have heard of their hole templates, Redan, Pit, Gate, Home. It was all the history of the place which resonated with me. If given the choice I'd play both, rather than North Berwick twice IMO, but I'm sure you will hear quite a few saying the opposite. I think North Berwick was like 120 pounds or something and you can't justify paying more than double for Kingsbarns that is for sure. However, I like variety and checking off another top 100 course was worth it to me.
Enjoy, as I certainly did.
