Is negligible flourescence okay?

How much does a negligible flourescence differentiate a diamond from one with none?

I am comparing two diamonds:

1.75 carat, G, SI1, HCA 1.9, no flourescence: $12,348

1.70 carat, H, VS2, HCA 2.1, negligible flourescence: $11,767

Any thoughts on the better choice?

Not at all. Terms like "faint", "neglijable" and "none" have the same significance in the language of differet grading labs at different times (I thing "none" and "faint" were replaced by "neglijable"... hope I am not turning these around). All mean - no fluorescence visible under grading condition, comapared to some standard inert sample.

When the GIA used to say "none" early every appraiser and gemologist was astounded they saw "some" UV fluorescence. After years of wondering why, the situation was cured by using "negligible". When there is none or very little, negligible, is a far better way to put it. Many old lab reports that say "none" are incorrect in a minor way.
