No - the only implication is that the UK wouldn't use so many (costly) resources for something as minor as a few stitches on a 3 year old.

But as a parent, it is YOUR 3 year old so you want the absolute best for them. The end result, I believe, would have been exactly the same had it happened here or in the US. Just I had a lot more confidence (at the time) seeing just how much was being done to ensure there was no scarring.

I would assume that while a broken chin would get reasonably fixed in UK, it would not involve "at one point there were 8 folks in the room.". I'm not a doctor so I can't be certain, but it seems plausible that in UK they would get adequate care but in USA they would eagerly "overprovide" services that are nice but carry a hefty extra cost.

In the UK you would never have a top surgon and 8 doctors and nurses dropping by to makes sure everything was OK for something as trivial as stitches. You'd have one person who would get you in and out as quickly and efficiently as they could. Whether that qualifies as 'lesser' is up for debate.
