Preferred vs Preferred Plus - What's the Difference?

I'm hoping to change my current plan. I want to drop all Premium Channels. But keep all other channels and services.

You list Preferred at 220 channels and Preferred Plus at 230 channels. I've gone through the Comparrison Chart line by line but cannot locate any difference in the channels offered.

What are the channel differences between these two offers?

Thanks in advance for your time and information!
