Do the north-American subarus (produced at the old Isuzu-Subaru plant, not Japan like are exported elsewhere) have significantly different quality?

I've driven a 500,000km 1992 Liberty (legacy) Turbo before with original gearbox, engine and turbo. A bit of a nerd fan of these early Libertys all of them these days have between 250,000 and 450,000km on them as a given.

Similarly there are many, many subarus running around in Australia with several hundred thousand kilometres on them and no major issues.

In Australia, Subaru engines are generally known for their reliability.
