I'm looking for the HFC.
But, I wonder which sell is good for my car.
ERZ is 200sell and Berk is 300sell...
What is your opinion?

What makes you say berk is 300 cell? I believe berk is 200 cell as well.

I heard it from the member Kyle(Houston)

Every resource that I can find points it to be 200 cell:

Berk Technologies High Flow Cat Pipes Nissan 370Z 09+

The Berk Technology high flow catalytic converters are designed to be much less restrictive than stock, letting you unlock some of that lost power while still serving the function of converting harmful exhaust gasses into something less poisonous. The Berk Technology cats have a 200 cell count spiral wound metallic substrate. The substrate is the catalyst saturated honeycomb-like stuff inside the cat that the exhaust gasses pass though that does the cleaning of the exhaust stream. A metallic substrate has thinner walls with less cross sectional area than the ceramic material used for the honeycomb in most factory cats. Thinner walls mean larger internal passages in the honeycomb and thus less backpressure. Each passage is called a cell and a 200 cell count means that this honeycomb has large diameter cells for low restriction. Stock cats usually have cell counts in the 400 range and thicker walls on the cells making for much more flow restriction.

Berk Technology downpipes feature high quality all stainless construction, pre-cat bungs for wideband tuning sensors, gussets, proper rear o2 sensor attachment and big bore smooth mandrel bends for good flow. The stock catalytic converters came in at 10.5 lbs. each, while the Berk Technology High Flow Catalytic Converters came in at only 5.5 lbs. each, saving a surprising 10 lbs of performance robbing weight from the front of the 370Z.

Details:

Diameter: 60mm (2.36 inch)
200 Cell High Flow Cats
5.5lbs each. Saves 10lbs over OEM

Thank you for your reply. I heard it is 200sell from Kyle(Houston) again.

Get the Berks HFC's for sure. I would have no others. I put down 310 hp to the wheels with those, K&N intake, and nst pulleys. Best cats imo..
