This comes up so often I’ve written about it. Bottom line is you need both, due to different clamping/let through voltages and the difference in voltage during a surge of an outlet that’s 30’ away vs. at the panel.
In terms of brand, ideally the best are the one’s that fit in your panel like a breaker. The leads used by surge protectors which are wired into the panel increase resistance and inductance which increases the let through voltage.
Here is what I recommend for surge protectors at the outlet.
