[Closed] Car suspension - comfort with control

I've started to look into buying replacement shock absorbers and springs for a Toyota Yaris which might be coming my way (not seen or driven it yet, but I've been told it needs new shocks).

I don't know much about suspension, but it seems that suspension kits from 'name' brands (such as Koni and Bilstein etc) are supplied with lowered springs (eg maybe 35-40mm lower) and probably firmer shocks. I presume this is because it improves cornering, but I think it would make the ride harsher, and possibly not as good for comfort on typical UK roads.

Is it possible to get suspension which is supple (for comfort over rough roads and pot holes) but which doesn't wallow or roll when cornering hard on B roads?

Is this a case where it's best to go for OEM parts rather than 'upgrading'?
