On the one hand, obviously a fair bit. On the other hand, since Vasuda Prime was such a ****hole, they were great at being IN SPACE. Witness the fact that even post-Vasudapocalypse, the orbital shipyards in Vasuda Prime were able to roll out 6000 Bakhas!
All in all the Vasudans are doing pretty well and are probably an industrial and scientific power on par with the Federation. However, like all factions in BP they have their own weaknesses, in particular some truly byzantine internal politics. Say what you will about the Terran half of the GTVA's failings socially or economically, its military will do its job and is highly responsive to political will*, whereas the Vasudan fleet is...well, while the Medjai are fiercely loyal to the Emperor, there's a lot of weird stuff going on in the rank and file fleet battlegroups. As far back as FS2, you can see that people like Admiral Ahmose were liable to play things a little looser than Terran admirals not named Bosch, and that situation has just gotten worse. (Who was Captain Apries of the Pesedjet anyway?)
While it might seem like the military and economic might of the Vasudans seriously outstrips that of their Galactic Terran brethren, the great weakness of the Vasudan people has always been their tendency to make everything incredibly complicated.
