What do you base your judgment on? I think it heavily depends on what you needed services for thus far. I know people who thought just like you - until they themselves or a relative really needed them. Then they changed their opinion. But even then it depends on what exactly the issue is, I know at least one serious cancer case who got everything they could and then some for free - and they had money and shopped around, incl. specialists in the US checking out if it was worth going there for private consultations paid out of their own pocket, who told them they had top specialists right in front of them near where they lived (in Germany, a university clinic).

I think variance is big and individual examples are useless unless you have the exact same problem in the exact same locality as someone else. But I think it's safe to say that anything falling outside standardized diagnosis may not work out so great. I had to do my own research myself and beat a professor's (of medicine) prediction and amazed a few other doctors with "miracles", but I did not actually do anything special, just what I thought was kind of obvious after some research. When you fall into one of the many blind spots your experience will be bad, if you fall into one of the categories which are "standard" you'll probably be one of those people who are very satisfied by what the system provides.

One has to understand how doctors are trained and what the system they work in forces them to do (and what not to do). Once you understand that you may get more satisfaction. For example, doctors prefer treating immediate problems. If you come with a long and varied history, they don't have a time for that, and often they would not know what conclusions to draw anyway - the body is complex and even if they had a hunch, the more possibilities there are the harder it is to diagnose. Also, expectations of expectations: Doctors know (sometimes learned the hard way) that people expect miracles or at least solutions from them when in reality they themselves often don't know.

Finding the cause of a problem may take months or even years of commitment (in retrospect, after a diagnosis, it's always clear of course, "why didn't we think of that sooner"). Few patients have the resources, the patience(!) and will to slowly and iteratively work on a problem, especially when success is highly uncertain. I only solved the one I myself had because I took some very radical steps that set me back income-wise for a decade at least and cost me a few social connections. The majority of people would have gone with "placebos", symptom-covering "solutions" for immediate problems, instead of choosing the great uncertainty (and when I started it was very uncertain indeed and everybody advised me to be "reasonable" and not throw my life away to chase ghosts but listen to the doctors). If I was a doctor I would never treat someone like me - because it would be highly unlikely that the person would be as extreme as I was and give up so much of their current life for very uncertain future benefit. So what doctors offer also is a mirror of what patients expect and are willing to invest (and I don
't mean money, the time and effort under uncertainty is much harder to bear).

By the way, my tonsils disappeared by themselves! I went to nose and throat specialists a few times during the last decade because during my long recovery I had plenty of throat issues. At some point they wondered why my tonsils where so tiny, and during the last appointment last year or so I was asked when they had been removed - they weer gone. I never had surgery, and I'm sure I still had them a decade ago. No use asking, nobody knows what happened. They were definitely never removed (or the doctor three years ago would not still have found them to be unusually small, and the next one three years later that they were not there at all).
