i've worked with fl studio a fair bit, and i've had the opportunity to work with protools recently as well. flstudio definitely seems a lot more intuitive and straightforward at a superficial level. protools has some layers of complexity that i'm sure allow it to be a much deeper program on more advanced levels, but it seems to me like flstudio is sufficient for at least the level of work that i would do. i'm definitely not experienced at all with either, but that's my impression
also flstudio would be cheaper probably so that's a plus
