This is one of Image-Line's better FL stock plugins. I use it a lot for plucks, but I've made leads in it before. The way the synth runs filtering, pluck, and onboard effects is pretty sweet. However, if you need a large range of sonic flexibility, this isn't what you need (Harmor is better for that type of thing if you want a similar GUI). As far as phat leads, I'd say Sylenth is better, but for being a stock plugin, this is actually really nice. I got this for free by updating to FL Studio 12.
On my old PC I did try FL Studio. I mainly disliked it, which is why I stayed with Ableton, however this synth certainly stood out. I loved the sound it had. I really want it to come to Mac so I can use it again.
