Jeff, there is a simple answer for your son's observation (IMHO). He probably grew up, a broad assumption I know, on Australian bacon (sic). That only makes it best because that's what he knows.
I grew up on Awmerikhan becan. It's only best because that's what I know. No disrespect to the becan I had in the UK but most of it was like ham slices here in the US, and dry to boot. I did have one good shot of becan on a place that promised to serve me a "proper burger" (that was in their slogan). Was pretty good becan, that.
I worked it out in the end, mostly you got served up 'Back rashers' while you were over here because it has become more popular in the last 25 years or so. If you wan't 'mirkin style becan here you have to ask for 'streaky' which is cured belly cuts just like you guys like it.
You can go to any deli here and get exactly what you want different cures, different cuts, smoked, unsmoked you name it, it's just the mass appetite for becan over here these days is Danish Back becan so that's what you'll likely get unless you specify.
Although Back is more lean I tend to prefer the taste of what we call 'streaky' and what you call becan too, but mostly I get served up back becan, unless I'm at home where we always have a stash of 'streaky', the becan, becan.
Most 'British' becan is actually 'Danish', go figure.
