Bill, an excellent question, but IMO, these are two totally different guns, both are outstanding in terms of reliability, quality, and accuracy. I would make my decision based on what the intended purpose is, and which one you feel is more comfortable and that you shoot better.
For instance, if you have young children in the house, the P7 is probably the better bet. If you prefer something lighter for carry, the P99 is the way to go.
