To elaborate on my own opinion on the use of metronome, though it isn't a very strong opinion of mine.
Metronome absolutely has it's place, but in general as far as I am concerned rhythm shouldn't be mechanically strict timely punctual, it should be organic, dynamic and flowing, and practicing with a real living organic drummer will almost always be the superior way to develop your sense of pulse and rhythm.
Rhythm in most cases should not be controlled, but it still should be intentional, and to the latter point, in lack of better alternative, a metronome might have it's place.
Also for certain music actual a strictly timed punctual rhythm is crucial, so in those instances practicing with metronome would be beneficial as well.
I guess my point is that practicing with metronome is a useful practice, but you shouldn't always practice with a metronome, and at any chance you get you should practice with a real drummer.
And in most instances a natural organic, dynamic sense of rhythm and pulse is superior to a strict mechanical sense of rhythm.
I suppose one man's sloppy, is another's natural, dynamic and organic, and one man's tight, is another's robotic, stiff and stilted/uncanny.
As said though some specific styles of music does call for a "robotic" rhythm.
