yup a good point
but if take a deeper look the 7,5k license can process say 1500-1700 x 18 Mpix imgs as its per 30 Gpix limited.
the 99 EUR version is limited to 2500 images and can use even 200+ Mpix cameras ( large cam )
For the speed from our testing we are 2-3 times faster on single PC
for the quality that is for longer discussion 
and they cannot process terrestrial laser data…
Not to speak about price if need process more than 30 Gpix of data… we are much cheaper in short and longterm…
