Quote from Rezzahan »Replicate creates copies of the spell via a triggered ability, which can also be responded to before the caster gets any copies. The copies aren't cast, so they cannot trigger heroic abilities. They also resolve independently with players getting the chance to respond in between whereas with strive you are dealing with a single spell and all its targets are affected when that single spell resolves. And of course, a single counterspell can stop the entire strive, with replicate you need one counterspell for each copy and the original (usually).
So yeah, replictae and strive are worlds apart.
