Well, the 2000 also has an internal tunher.  As far as which radio, 
depends on a couple things, the price, and second, do you want 2 and 440 
all mode and dual receive for these bands and so forth.  I have both rigs 
and like them both.  I think the 480 is one of the most accessible rigs 
you can buy and I sure do like mine.  You wouldn't go wrong on either one.

As far as the f6, I also have one of those, and as some one else said, if 
they discontinue it, I'll go grab another for a spare.  I like the radio 
that much.
