Nomenclature on catalytic converters is as follows. CPSI is the acronymn for cells per square inch. CPSI is the description used worldwide despite the metric system.
So therefore 400CPSI, 300CPSI, 200CPSI, 100CPSI and 0.00 CPSI equate to sqeezing 400 small squares into a 1.0" sqaure all the way down to only 100 square cells per 1.00" square. 0.00 would be a straight pipe or catbypass pipe. Therefore as one goes dwon the scale from 400 cells per inch >>>to>>> 100 CPSI you will be less backpressure and restriction per unit area given the same design criteria an washcoat.
Your last question " What is better" depends on who is asking what is better?
The EPA & Federal Government would say 400 cells is best as it scrubs exhaust the very best and allows the least pollutants and makes the car the most quiet.
For car enthusiats like all of US.........going to 200 or 100 cells or to NO CAT if that is allowed or permitted is the way to go or atleast head in that direction if maximum power and moer sportscar sound is desired.
I hope this cleared things up.
