MOM and MAVEN were just about simultaneous (arriving at Mars two days apart), but they weren't comparable. MOM's primary mission objectives were things like "navigation." MAVEN would be NASA's 3rd orbiter at the time, to say nothing of the 4 or so previous orbiters, and so they weren't trying to just repeat earlier things.
Now, if you compare launch costs, you get a better feel for the differences. Those were about $43 million (MOM) to $187 million (MAVEN). But MAVEN was almost twice the mass.
SpaceX will give you a Falcon 9 Full Thrust launch, fixed price, for $62 million, which can launch something twice as big as MAVEN to Mars.
So SpaceX and India are price competitive on a kilogram-to-GTO basis.
