The body style and the way it hangs when strapped on is VERY different... some find this a non-issue, others a positive, others a significant negative. It just needs to be taken into account when making a purchase decision

One of the reasons I flipped the (truly) GREAT F BN5 I recently had is because of this. It's really quite different how much closer the headstock is to your body when on the strap.
Like Ken says, it was negative for me, but only because it was so different from what I was used to and most of the rest of my stuff.
If, on the other hand, I just had one bass, having the neck positioned closer to your body could actually make it much easier to play for someone with smaller hands and/or less of a reach (or maybe easier for anyone). It's different enough it seems intentional, and that's the first reason that pops to mind anyway.
The one thing that is a bit odd about it, however, is there is a noticeable diff between seated and strap'd positions, which I'd think the builder would want to make that the same. Seated, it was more like the rest of my stuff, but strap'd it really moved it in on me.
Not a huge deal, but I did notice it, at least.
More on-topic, however, I don't think I'd run right out and refinish a new F in poly, BUT, if I did have one refinished, I'd definitely do it in poly. I do like the durability. Unfortunately, I recently was able to "test" this, and poly really does protect in a BIG way.
