I guess it just comes down to aesthetic preference then.

If there's motion blur on something I'm tracking in smooth pursuit, it doesn't seem particularly objectionable. (I guess I also wonder how accurate the eye's smooth pursuit is -- especially with fast objects in video games, surely it's only approximate and therefore always somewhat blurry anyways? And even if you're tracking an object's movement perfectly, it can be still be blurry as the video game character's arms move, its legs shift, its torso rotates, etc.)

Whereas if there's a flicker/strobe effect, that feels far more objectionable to me.

At the end of the day, my eyes are used to motion blur so a little bit extra on an object my eye is tracking doesn't seem like a big deal -- it still feels natural. Whereas strobe/flicker seems like a huge deal -- extremely unnatural, jumpy and jittery.
