So optical did indeed surpasses the laser ones?
First things first, both are optical, and image correlation sensors, the difference is just simply the illumination source, the PTE is an exception to that though as it uses two VCSEL's(one for x, one for y) and the "doppler shift" to determine travelled distance.

AFAIK laser sensors have a lot of acceleration, this is why optical sensors are usually better. Laser sensors usually have higher DPI, but they aren't as precise. It comes down to personal preference TBH
I just quote myself:

It might seem kinda pedantic but it bugs me, it doesnt have "acceleration built in" its CPI are fluctuating and in most cases leaning overall more towards an increase with speed, it simply is dubbed as resolution accuracy(or error if you go "from the other side"), which obv. isnt perfect on any product(which includes LED illuminated sensors[optical]), just to varying degrees. It also is only partially caused by the laser illumination, its just simply harder to achieve a good resolution accuracy with it while keeping the pricepoint in check.
Which would be the case with the A9500, A9800 and all of its offsprings, A6010 and A6090 on the other hand have lower resolution errors, though they have other problems.
Edit: Oh, and ofc the surface also plays a part in that regard.
