As someone who has also 'been around' I'd have to say that both have their strengths, and weaknesses. But there is one weakness that all martial arts share, and that is they are practiced by mortal men, and women. When you get right down to it, you don't need to be a grappler to takedown the striker, or have a bunch of your friends with you to beat the grappler. You don't even need to know anything about martial arts. All you need is to pick up a lead pipe, and hit the other person in the knee as hard as you can. Or run them over with your car. Or push a piano out of a window from the top floor of a building to fall right on top of them. Or poke their eyes out with a fork. Or any other number of things. Hell, do nothing, and eventually the other person will kick the bucket on their own.
With all that in mind, just do what it is you love.
