That's up to you and what you need as far as concealment, weight, holsters, etc.
The LCP is a great little pocket gun as the P230 may be a little big for that. You'll get great shooting comfort and handling out of the P230 that you may lack in the LCP. Better sights on the 230, better sight radius, but it is a bigger, heavier gun.
What are your needs? Which gun meets those needs best?
