I agree. For me personally I mostly only care about single thread geekbench variant, I believe it's an excellent proxy for general performance of a CPU. Multi thread geekbench (or other benchmarks) for most purposes and for most people, it's kinda useless. You just need to know that you have a quite a few cores on your computer and that it will have enough concurrency for what you do. But single thread will make whatever you do actually faster.

There are plenty of things for which the results of single-threaded benchmarks are completely irrelevant, like the compilation of a big software project.

There are also things that are well-correlated with the single-threaded Geekbench result, like how responsive will appear an Internet browser, but for many professional uses the multi-threaded performance is much more important than the single-threaded performance.

For many CPUs, and depending on the computers in which they are installed, the single-threaded and multi-threaded results are completely uncorrelated, because during the multi-threaded benchmark the clock frequency in some computer may drop even 4 times (there are Intel CPUs with a so big ratio between the maximum turbo frequency and the base frequency), while in another computer it might drop only by 20%.
