5th, then Extreme, both for the same reasons.

5th was the end of the era, it had all the greatest songs on the machine.  It had the best character (Alice), and it never got old, because you could just play it over and over and over.

Extreme was pretty much the same way.  The end of the "MAX" era, all the best songs, old songs made a comeback, largest songlist ever.  Made it very hard to get tired of playing it.

I'm not sure if I like SuperNOVA 2 yet.  SuperNOVA 1 was a big dissapointment for me, I miss the Dancemania stuff.

Also, take a warning with this unlock code. It seems strange to me that it would be released now, when there's so much controversy over eAmuse. They may very well be trying to pacify those that actually want the system, because the system's implementation is further away than we could imagine.

I'm going to assume that you already know the system was already implemented in the US and just ignore that part.

Next I'm going to point you to the history of unlock codes for all previous DDR machines.  Any that had multiple teirs of unlocking were released in staggered sets, just like this. 

Don't bother going to the Naperville location.  Everyone still only plays In the Groove, so they turned the music way up on it.  It isn't possible to play the game anymore because you can't hear the music.  I told an employee, but he didn't care.

It is not a dedicated SuperNOVA 2 machine, the pads are not new, and neither is the machine.

e-Amusement is not machine dependent, it is another add-on you buy for the machine. 

Just got back from BZN.  No e-muse.  The stuff was there alright, I got a card, I was able to put it in the machine, but it didn't do anything.   There was a big error message on the screen that read something along the lines: "YOU CAN'T USE E-AMUSE NOW!"

I was not happy.  The pads had a few moments that were unresponsive, so I decided I'd cut my loses and only play one game.  Overall, I give it an F- for fail.
