Depends on your goals. SU are more expensive than a reload, but reloads require hardware. If you fly a lot, and plan to stay in the hobby, reloads are far more cost-effective. However, that assumes you build them correctly and don't cato your hardware. Also, losing your rocket means losing your hardware, so tracking becomes important, as well as dual deployment for closer landings.
People who stay LPR may never fly a reload in their lives, and that's cool. But if you are planning on certifying and moving up to bigger and more powerful rockets, then reloads are a must.
Another thing to consider is where you buy motors. If you buy SU from an onsite vendor, then that is way cheaper than paying HAZMAT fees. But many reloads ship HAZMAT-free, depending on the size of the grain, whereas most larger SU motors require HAZMAT.
So, if you come back with answers to those questions (where do you buy? do you plan to grow in HPR? are you willing to invest in tracking an DD? do you fly often or plan to?), then you might get some more fine-tuned advice.
