Test suites reflect the ability of finding - more or less difficult - key moves
(decisive moves, most often). This is more important for *analysis* than for
gameplay... but of course also very useful during gameplay. I.e., if the
opponent made a mistake, and the engine takes the chance to decide the game
immediatly.

It's probably a matter of the best balance.

But sooner or later, I think there will be (or should be) a "settings switch"
normal gameplay / analysis in chess programs, to change several parameters to
adapt to these to major ways engines are used. For example, more "test
suite-like" focus on tactics for the analysis mode.

Analysis is IMO the most important way engines are used. Eng-Eng matches are not
that important as it may seem while looking into the fora. Most chess practicals
(i.e. club players) usually don't post much on message boards. They are too busy
with opening preparation, and analysing their opponents games, probably... :o)

So the best engine might be the one which analysis best, not the one which is
best in comp-comp games. I'm beginning to see comp-comp games as a sport (only),
but people usually don't buy cars to compete in car races.
