I've researched them both.  Looked into most all of the other alt coins and NXT just makes sense.  Congrats on the first 73 who were smart enough to invest in it.  They will be rich.  They deserve to be rich.  As it is, I am happy to buy NXT off them for a mere $.07 per coin.  Forging blocks is easy.  I've got about 10,000 NXT and should forge a block about every ten days.  Simple math can figure this out.  Even more, most of the original stakeholders aren't even forging which means I'll get a block even more often, but NEVER less than one block every ten days.  Try that in bitcoin.  I couldn't afford the equipment to even come close to that.  NXT is simpler, greener, fairer.  It is truly 2nd generation crypto.
