It's kinda true but also not at all. In general, having better single thread performance means a more reactive UI and snappier feeling because blocking operation gets executed more quickly. On the other hand, many modern software having been extremely optimized for multi-threading and not all categories of software benefit that much from faster UI thread. If parallelization isn't too expansive, throwing more core at something can make it actually faster. And the big thing you leave out is that it all depends on how well the software is optimise, how much animations it use and things like that. My iPhone has MUCH better single-thread performance than my old PC, yet it feels much slower for almost everything. And this is exactly how I feel about Apple Silicon Macs. On paper, impressive performance. In actual practice it doesn't feel that fast.
