I'll claim that unreasonable invasions are bigger problem under Japanese
rules than under Chinese rules.

3 examples of silly invasions and reactions to them.

Example 1: WeakBot50k vs some single digit kuy player at KGS2 time (now
WeakBot50k is 20k, but at KGS2 time it was < 30k).

WeakBot50k is very weak bot, but opponents kept passing and sometimes
needed some time to think whether to pass or respond. Surprisingly often
opponent passed when should not and WeakBot50k lived or increased live
group size. So my conclusion is that this was stressful for stronger
opponent and too often failure.

Example 2: WeakBot50k vs me: It doesn't take that many moves to achieve
unconditionally alive status so games end much faster and easier than
with example 1. Of course this is attributed to WeakBot50k knowing when
all is unconditionally decided and then passing. Still much easier way
to end game. (currently running WeakBot50k version resigns when it gets
too much behind as decided by 100 random games)


Example 3: Me vs another human with 7:31 sudden death game with Chinese
rules.
Game was over and there was not much time left on either of our clocks.
Opponent tries silly invasions, but I continue simplify positions and
thus being able to answer faster and faster and eventually position was
mostly unconditionally alive. At that point opponent resigned position
being dead simple and having less time on clock. I used less time than
opponent and eventually could have passed for free. Had game been under
Japanese rules I would have been 'forced' to think whether reply was
needed and thus think a lot longer time for replies and possibly lost on
time because reply would have been needed probably too often.

Conclusion: Under Chinese rules and limited time player can end game
easier and faster than under Japanese rules when opponent tries silly
invasions.

Japanese: harder and more stressful
Chinese: easier and less stressful

Also being able to simplify and achieve unconditional life as fast as
possible is a skill too.
