Is Career Banking for me?

Currently, I am a at a target university pursuing a major in finance, I am conflicted with whether I want to be a banker or work in L/S equity. For many years now I have been interested in the markets and actively trade but from what I have heard there is zero job security in the hedge fund industry. I consider myself to be analytical and very competitive. The main reason I enjoy trading is because of the competitive aspect of it. In senior banking, a large part of your job is bringing in deals and closing them and it is really a sales job at that level. I think that I would enjoy sales as well because that too has a competitive aspect to it and as I said before, I enjoy anything that is very competitive and involved winning or losing. I also like being a leader and want to one day be in a position where I am leading many people. This becomes another plus (in addition to job security) for banking since in senior banking you are going to be leading a pretty large group while as a portfolio manager you will be working with a small group. With all that said, would it be better for me to pursue being a career banker or go down the HF route?
