Yes, very much so, from a technical perspective.
Among other reasons. In a rock band with a rock sound, all the instruments much more naturally fall into their own spaces. With metal, especially the detuned variety, the demand for spectral and dynamic territory is massive, with everything trying to be the biggest baddest thing in the mix, the balancing act required is far more merciless and delicate.
otoh, 'precise' is easy, after a fashion; its pretty clear whats precise and what isnt, whats viable and good enough and whats not. 'Energy' is much harder than precise, imo, because its a different sort of judgment call, much blurrier and taste-dependent. Metal is more sounds tight = right, rock is more feels right = right. Dont think that the latter is easier than the former!
