how can I compare the packages without getting looped all over the [Edited] place

I just want to explore all of the channels on the ultimate vs TV plus (etc) packages. Simple, right? Not on Xfinity. It keeps looping me or making me sign in (which I did)...and then it still won't take me to a simple comparison table of what TV channels are included in one vs the other. Simple request. I thought. And why did I have to sign in just for this?! Xfinity is SO frustrating.
