Which flight provides the best experience on the A380 suites?

Looking at the most common destinations, it appears SQ flies them to NRT, SYD, and LHR.

I think both SYD and NRT would be far shorter flights and perhaps these routes do not make the most experience out Suites Class? On the other hand, the LHR flight seems to always have astronomical prices compared to competitors.

Anyway, I'm just planning for potentially trying this out later for 2025/ 2026. Trying to cross off planes on my bucket list. I've actually flown on the A380 thrice (TG in Y, and OZ in business) but only on short hauls.

(How does SQ's Suites class compare to other A380 operators?)
