There's no need to compare. They are all outdated models. Sony's 1000 had better be upgraded to 1500 at the same price, and Panasonic's 10000 small horse-drawn cart is useless. The advantage is cheap and bluffing. Panasonic 73 has better performance and awkward price. If you add more, you can buy 180.

In short, Sony 1000 can be considered for small wedding applications, and 198p is recommended. Professional applications need not be considered, at least Sony 198p or above models should be considered.
