I had the same experience.

Only few things came close since: QNX, my M1 MBP when it was new and a fresh MXLinux installation (no idea how they do it, maybe some low latency scheduler?)

Those felt similarly instant GUI-wise as BeOS did, while unfortunately current MacOS and Win11 feel glacial compared to it.
