Nah. Not even close. It's good, yes, better than Vancian and such IMO, but it doesn't hold a candle to the systems in Mage, Ars Magica, Unknown Armies, or Witchcraft.
I've read, but not played Mage. Didn't think much of the system really, but I believe that was because of the setting/ paradox. I was thinking of trying DA Mage to see, but didn't think it worth it, since I'll never play either.
SR IMO is better in execution, Mage only holds the edge because you don't have spells. That's also it's weakness, since it's more work.
Ars Magica likewise was an elegant system (which I read and played, though don't recall the version) that I don't think really worked that well in game. (for me & my group)
Unknown Armies. I played a one shot where I was a chaos mage/ random guy, whatever. I thought it was a bad system. It's basically point based, with unique ways of getting points from what I played. Granted the DM of the game didn't help, but...
Never played/ read/ heard about Witchcraft, so I've no comment there.
I like D&D magic for D&D. I like SR magic for SR and I think Ars Magica's system was perfect for it's setting. Each has their advantages and disadvantages, but fit their games really well.
I don't like Mage or D&D's magic for the fact that they don't (IMO) handle little uses of magic well. I like using magic in everyday life (uh, in game

and D&D's fire & forget and Mage's adjudication method don't fit that for me.
