I switched my personal page over, then went to switch over my company page. I didn't like either, but so far left them, assuming this will be a permanent change in the near future anyway. While I'm here, I also hate the new home page. I don't need stuff from google plus in there... I have google plus for that.
Anyway - the channel pages- putting aside stuff like severely limited customization (only color we can change is the background now? We can't rearrange the 4 theme layouts in any way? We can't keep our info expanded by default?), what we CAN do is not clear. On my company page, I tried to change the background (since it was lost in the 'upgrade'), but every file I tried, including the one that was the BG on the old channel, didn't ever work - I don't know what bcause I was never given any helpful info like file size or format restrictions.
I don't like the comments being hidden as much as they are. I don't like how I can't see my friends at all (at least I couldn't find them), and only see the number of subscribers I have, but can't actually SEE my subscribers...
What's the point of even adding friends and subs if you can't even see them? It seems the common view on the new channels are - don't change them. They give everyone a cookie cutter, self-centered, boring page. No customization. No community.
