Pros, Well there really are none. Well, at least not in my opinion.

Cons Fuel sensitivity, poor combustion, uneven flame propegation, etc.

For high compression go with flattops and a small chamber head.

Domes can also create valve to piston clearance issues.

I vote flat tops and smaller chambers.
