I know comparing different focal lengths is like comparing apples to oranges, it depends if you like more apples or oranges.
I'm in the crossroad as I find the 50mm a tad too long and the extra stop might be useful sometimes. Then there's the rendering of the image which is magic.
On the other side the fa 35 is like a normal lens (imo it should be the kit lens of pentax cameras), the the shorter focal length might make up for the smaller aperture.
I agree a prime should be offered as a kit but only as an option, the zoom is much more attractive as a kit lens to new customers.
You already have a 50mm f1.4 screwmount so logically you should get the FA 35.
With regards tospecifically answering your question, it's nigh on impossible to give you a definitive answer. There can be a world of difference between the two lens's depending on what you want to shoot. f1.4 is nice to have but it is quite limited in it's usefulness because of such a shallow DOF. The 35mm is useful as a portrait lens if you are in confined space but they are both good for portraits. They are both useful for landscapes. f2 is plenty fast enough for most applications, if not, that's what flashes are for (and chances are you would need a flash with the 50mm as well for the same shots).
I could go on and on but I'm sure you get my point.
I didn't vote for obvious reasons.
