This is a little hyperbolic. There have been occasional superior alternatives but "often" is kinda silly. By and large, the best products won - and that is despite accepting that Intel acted in anti-competitive ways in the past (Cyrix et al).
Agreed, somewhat, but you are conflating "product" and "architecture". I specifically meant architecture.
Intel was usually at least one process generation ahead of competitors, and often more than that. With Moore's law still going at full tilt, that meant not only more transistors, but also faster transistors, completely overwhelming the architectural deficits.

Hmm...just off the top of my head: Motorola 68K, MicroVAX, LSI-11, SPARC, AMD 29K, Power, RISC, MIPS, Transputer, Alpha, HP-PA, ARM for desktop, Motorola 88K, Fairchild Clipper, etc.
I'd be hard-pressed to name an architecture that wasn't superior to i386. But architecture did not matter. With Moore's law no longer also getting us faster transistors, it might matter again: https://rodneybrooks.com/the-end-of-moores-law/
