Generally speaking, I associate fanboyism of any type with the kind of "blind consumerism" I tend to judge people for. To the credit of the M series detractors, outside of Apple's ecosystem, ARM isn't a real competitor yet in the consumer space. If you aren't using macOS (or possibly Asahi), the M series just isn't consequential to you as an end user.
ARM certainly has potential. Microsoft's initially half-assed attempt at providing compatibility, paired with hitching their wagon on Qualcomm isn't helping consumer adoption. In the enterprise we are seeing some progress, as the prior decade's push for platform independence has enabled software to be more easily ported to different architectures. Maybe we'll see the datacenter move to ARM followed by the consumer space?
M3 has both perf/watt crown AND raw horsepower crown.
AMD/Intel still can't produce a passable fan less laptop in 2024 since the M1 Air came out 3.5 years ago.
