Hmmmm.... Lesseee....
No Monarch has ever lived under such scrutiny, that's for sure. Royals are strange people, as people, because they don't live a normal life, don't have a normal upbringing and have an unusual set of circumstances put upon them. If the jobs being done properly, then it isn't really a job that I'd want at all, to be honest - it comes at the price of subjugating your personal self UTTERLY to the needs of the state that you are the head of.
I think you can say that Her Majesty has certainly done that.
As for the new crop? Well, I don't rate His Royal Highness, the Prince of Wales, particularly. I think that's who you're referrin to as Chuck. Charles is a particularly inauspicious name for a monarch - if you check the list I gave you ealier you'll see that. I personally don't know if he has the "right stuff" but we'll find out, I suppose.
His Royal Highness the Duke of York is a different matter. I personally rate Prince Andrew, because during the Falkland Islands conflict he was actually serving as a helicopter pilot in the Navy. He disobeyed a direct order, flew into a hilltop under fire and extracted a bunch of guys from a hot LZ. That takes balls... A LOT more balls than any of your recent Presidents have displayed. Let's be honest, pretty much ALL your recent Presidents have shown their TRUE worth by rabbitting when their country called.
His Royal Highness the Duke of Edinburgh is what I've come to expect from the third son of Royalty. Everybody focusses on the "Heir and the Spare" that is the Heir apparent and the next in line after him. A third son comes a VERY distant third in a Royal household, so no wonder he turned out to be a bit of misfit. Possibly gay, even. Who knows.
I'm not sure which of the last two you meant by "chimp" - again, I think you might be confused with George Bush who looks more like a chimpanzee than his father did. As has been pointed out in less than flattering terms recently and often.
Diana? I thought she was a social butterfly and a bit of a lightweight, and I was constantly tempted to ask her what the bloody hell she expected when she signed up for the job. As much as I regret her tragic death, I am relieved she will never ascend the throne as Queen. That would have been a TRUE disaster - since I doubt she was capable of attendin to the unpopular necesseties of ruling as opposed to whichever popular "warm and fuzzy" issue was flavour of the month.
I understand she was one of the worst Royals to have as your honorary CO. Princess Anne, apparently, was a very good honorary CO and often went into bat for her regiments during budget cuts. Prince Philip (The Queen's consort) is apparently a good honorary Regimental CO as well, I understand Charles is ineffectual. That's pretty much all I know.
