Which felt more challenging? 25-man by about a mile and then some. Really, the 10-man heroic bosses just rolled over and gave loot. Ragnaros was a tiny bit challenging, but that was because we tried approaching it in an overly complicated manner (ie., tried to carry over our 25-man tactics).
There's really no argument even to be made that 10's are at all harder or "overtuned." They're easier for a multitude of reasons. And that's not a bad thing, considering some of the limitations.
