I haven't played a ton of Fender 5 stringers out there, but I did just A/B one the other day with my 35" scale much more expensive Mike Lull. The Lull has a tremendous B on it, so it made for a good comparison.
I was surprised how much I like the Fender's B even with the 34" scale. It sounded really great and had similar tone to the rest of the strings (most 34" scale B strings out there I've tried sounded way different than the rest of the strings, including the Sadowsky Metro I had for a while) and felt great under my fingers. The action was considerably higher than my Lull though and I don't think it would be able to quite match the low action my Lull can get without buzzing, but my Lull can get scary low for a jazz bass.
For reference, the Fender was an American Deluxe, not a standard, and had taper-wound strings, FWIW. Definitely gig worthy and I'd be proud to own that particular one. Can't speak for all of them of course.
