Battle of the sharp gf's

I would like to buy a sharp gf 777 909 999 or 1000 but don't know the major differences between them all any input is much appreciated like of the 4 whats most powerful ?
Best all around bass ?
Are their any features 1 has that the others don't?
Price tags they all seem to be lower on the 909 is there a reason why ?

I'm partial to the 1000 for its look but looks are whatever I want performance

The 999 &1000 are both the best looking and have the most features, also have the big vu's
They also seem to sound better than the others as well, but both carry the biggest price tag with the 1000 being top of the tree price wise and your have a hard job finding a nice one
