SeenItAll is totally correct, in my opinion. Sane, common sense & factually correct answer. There is no point comparing ATCOS in Europe & USA. The job & its idiosyncrasies are very different. All, in general, do a fine job.
I would only criticize the US "clear to land", when that is clearly not the case. However, I have never worked there & do not fully understand the thinking behind it.
Keep up the good work !
