is fuji velvia 100f really bad?

i just brought 20 rolls of velvia 100f ( 120 size ) in and was search
net for reviews.  i badly found people tend say that velvia 100f is
the worst in the family of velvia ( the others are velvia 100 and
velvia 50 ).  i will go tour and my question is, should i take some
e100vs instead?  ( there is no velvia 50 nor velvia 100 in the local
market and i get no time to buy them on the net ).

thanks.
