Soon i'll renew my main electical panel, 200amp.

The electician suggest me to put a surge protection module on main distribution panel.(Seimens i don't know model number).
This has the advantage to protect the entire house.
These module has a protection capacity of 1600 joules this is an option of 300-400$ range.

Does it worth it?
Does some of you already have it ?
What are de pro's & cons of it vs small unit like: Monster power HTS 1600, 1800...HDP..2500 ?

my first mind is: main units give a fair protection (1600 joules) to entire house, vs a better protection (5000-6000 joules) for only specific electrical equipment on the house.

I'm living in Quebec, where the power utility is stable.
Your opignon please ?
