I have both and they are both super fun. You can't go wrong with either. Here's my 2 cents.
FR: Ridiculously playful. Stiff enough to hold its own even when charging groomer. The elliptical turning radius makes it fun out of the park. It carves very well even for a completely symmetrical ski. They are light, very poppy, and although it is a mid-stiff ski, the rocker (there's a sit load of it by the way) allows the ski t butter quite easily. I ski predominantly rails, and the thick edges don't hurt. They're crazy durable.
Sparknotes: fast, mid-stiff, poppy, and yet somehow buttery.
L-Toro: Super soft. It has much less rocker than the FR, but still enough to notice. Wider platform lets you take it into fresh with ease. And while it is a directional ski, it got chattery when I got to higher speeds simply based on the softness. In the park, bigger jumps can be done, but keep in mind that they are a soft ski. They kill rails, though. Presses are effortless, and if you've ever seen AD ski, you'd know that these skis butter like a dream. They are, however, a teencey bit slower than the FRs.
Sparknotes: Soft, playful, Buttery as fuck
To the extent that each trait endows each ski, I would say its a dead tie, just a little different. It matters what/how you like to ski.
