With no need of a power conditioner or surge protection
Consistent with the NEC and the recommendations of in-panel surge protection devices, they are not replacements for surge protection at the point of use. In particular, the let through, or clamping voltage, or panel mounted protectors is around 400V, but the surge protectors clamp lower. 180V in some cases, and may activate faster than the panel unit if they have enough series inductance.
Having typed that, please do whatever makes you happy, but it is incorrect to say that a whole-house surge protector is a substitute. It's an addition.
