Certain aspects were better, yes. That's because the Soviets made different trade-offs in the design -- variously because of doctrine, time constraints, availability of exotic materials (and the ability to use them in manufacturing), and "helpful" direction from Moscow.
The MiG-25 "Foxbat" is a famous example. To succeed in it's role as an high-speed interceptor it should have been made from titanium. But it's a very expensive and difficult metal to work with, so temperature critical parts were instead made from stainless steel. In the west there were lots of jokes about it rusting in the rain and the use of vacuum tubes, but tubes allowed it to have a very powerful radar. Plus that's what they had to work with (the Soviets having great difficulties making high-current semiconductors).
