I like Apple at its best, but I wouldn’t say they’re the best in every (or even nearly every) category they’ve entered.
Yes they have iPhones (top range, even if they have competition from top range Android alternatives), iPads (peerless), Apple Watches (dominant), iPods dominated the MP3 market back when that was a thing anyone cared about…
But they also make really weird mice (Magic Mouse 2: charger on the bottom; many models: one button; Mighty Mouse: scroll nipple; iMac: unergonomic puck), the Apple TV and HomePod are nothing special (the latter is a pity, given I don’t trust their Voice Assistant competitors), and the device power cables have been infamously fragile for a long time.
Some improvements like fit & finish, tolerances, endurance, so on are not visible on paper. Others like battery life and weight are visible on paper. When these combine with the xOS (where x={mac, i, iPad, tv}) ecosystem, whole thing becomes visible or palpable, one may say.
It's not an ubiquitous thing to have in technology space, and only possible with tight integration Apple provides, and strives to keep.
Doesn’t mean something bad is happening, yet.
