The biggest problem with Franchises is that you are restricted by their business model, it may be good but sometimes you are not able to do much.
One extremely important factor to consider when looking into a franchise is, what is the expected investment of time per week, and what is the projected level of income. Even a franchise operation that offers a well-known brand name and a comprehensive support system, will still require a lot of effort on the owner’s part to open and operate, and a considerable amount of time may pass before the owner breaks even on the investment. This holds even more true for a lesser known brand, with weaker support.
Franchising would be your better option, since you no longer have to start from scratch with letting the people know what service or product you are offering. If you start anew, you'll have to put in a lot of effort and money on advertising and things like that.
