I have 2 tony franklins and 2 Fender jaco artists, so I can recommend either one with certain reservations (details on request). Among those is they're both a pretty expensive bass, which might be out of your budget. If you can find either one used, though, for a good discount they're both ideal.
As for the tony franklin, the only big problem is has is neck dive. It has ferocious neck dive, though that's characteristic of the P bass generally. The TF comes with traditional tuners and drop-D tuner too which adds a ton of weight to the headstock.
Other than that, I admit my tony franklins get 99% of all my playing time now, even though I love the jacos.
Another option to consider is Carvin/Kiesel, which I have the most experience with in terms of fretless instruments. I had 3 at one point in time and they were absolutely impeccable in terms of build quality and QC, etc. The best thing about them is fretless is a no-cost/no-hassle option, unless you do something like the fingerboard finish (which they call the "hard as nails" option), or lines/dots, exotic wood etc. The only drawback there is it takes forever to get one, and I think their backlog is pretty substantial right now.
Those are a couple options from my own background I can comment on, beyond the less expensive ones from Fender and others, which are great options for a first FL also.
