More powerful Aircraft

Can SU-30's beat the Eurofighter?

Or can the J-10's Beat the Eurofighter?

Can somebody give your opinion and discussions regarding who is more powerful...

I am greatly confused with my research...

yes and yes. ofcource they would have the ability to down enemy fighters. i remember seeing this picture of a p51 mustang sim-dogfighting an f/a-18. and the p51 pilot actually managed to put the f/a-18 into his kill zone.

europeans historically have better trained and experienced pilots, whilst it also has better avionics, this will give the eurofighter an edge in aerial combat, but many other things should be considered. such as strategies, tactics, ammunition and the crew who serviced the plane are just a few examples which will affect the outcome of aerial battles.

Su-30 is a rather heavy fighter-bomber, Eurofighter-Typhoon is a much lighter fighter aircraft. Su-30 and Typhoon are not same kind of aircraft and are made of different type of tasks. J-10's size and role is similar to Typhoon. Both Su-30 and J-10 are 4th generation fighters, and the Eurofighter Typhoon is an upper-end 4.5 generation fighter with capability comparable to F-35 Lightening. Of course Typhoon and J-10 and SU-30 never fought heat to head in real life, but we can assume J-10 and Su-30 will be at incredible odds fighting against Typhoon.
