Depends on how you drive at the end of the day, and the rest of the front suspension components. I gave you the 'safe' option as a point of reference.

Slight toe in on the front will increase your stability, slight toe out will increase your turn in.

Most racers use the effect of camber thrust on a FWD car to aid turn in, so setting parallel or slight toe in, is the option we prefer for people who dont know what they want.

I use toe out on cold days to scrub the tyres and get heat into them quicker giving you an advantage, and in longer sessions/events use toe in to save the tyre and have a more comfortable day.
