What makes more sense to get for someone who's been only doing a few months of photgraphy?

A single lens that is flexible at handling a good range of focal length and still have a good aperature size,

or three prime lenses with a larger apperature, but at a similar price?

I have the budget to get either one or the other. It just feels more convenient to have a single lens that can handle the job similarly to three primes that you have to carry around, if they cost about the same in price.
