While I'm a huge Fender fanatic and own many, my lust only applies to 4 string passive Fenders. I have never liked any Fender 5's.
First thing I'd plant in your hands would be a dual pickup StingRay 5, second would probably be a Spector NS5.
Had to laugh here, I can't stand (or for that matter play) a five string. I do own one but its a Yamaha. But think of even some of the great "boutique" basses, Sadowsky, Lakland, etc...what are they and where did they come from? Sadowsky basically made his name "hot rodding" Fenders, same with Lakland and most of there high dollar offerings are still, not so much copies as Custom shop quality Fenders.
And to think, Leo was not a musician, but he built/designed some of the greatest axes we have. Staying in the bass realm, just in case there are guitar players lurking. Its hard to find any thing wrong with a Music Man or a G&L, and even those improve on his original name and design. There is a reason that when he sold Fender to CBS back in the 60's that they never had much sucess with anything other than Strats and Teleies, Jazz and P's. Even now, some marketting guru will drag the Mustang, The Jazz Master, The Jaguar out of the closet and flog it in the hopes of gaining "market" share, and they go away....again. But The J & the P, the Strat and the Teleie stay....that what they call a classic. Transends generations.
