I think either of three methods listed by you do not really present the exact quantification of your mental performance. Your performance on these tests will most probably depend on your interest in that particular kind of test. Therefore any results that you may get from these tests will have that subjectivity in them brought to the entire process by your level of interest for that particular kind of test.
One big advantage of the three tests I described is that I usually get very good binary outcome—yes or no. It’s not so with most other computer games, or other tests I tried. And they’re all quite pleasant activities—even if I wouldn’t necessarily want to spend an entire evening playing Quake 3 or doing go problems, I’m usually quite happy to spend 10 minutes on them.
