Not familiar with the linked machine, but I notice that its speed appears to be variable only within a somewhat limited range. Don't think that would be a problem though. As the PC is merely another type of random orbital sander this one could very well be as good or better for detailing.
I use a similar Bosch unit and it seems that the AEG has everything to be excellent. It has enough power, the necessary speed and most importantly, excellent pad throw.
