White,
Different, maybe 'newer', technology in the construction.
Whether it is 'worth' it or not, that's up to you.
By the way, you can get the same 'effect' of a 'bass taper' just by going up a line size. That's all this is, a 'heavier' front section. Plain old weight forwards are a bit less costly, in most cases, than 'specialty' lines and they will work just fine.
Good Luck!
