When significantly more devices were running at 9.6 instead of 100 on the C-8 vs. my C-7 I bought the rectangular version:

I tried them pointing parallel to my home's main N-S axis and at 90 degrees. I gave them each over 2 weeks in each direction and I'm still worse off than the C-7. Below is a link where I posted a screenshot of my charts showing how many are are 100, 40, 9.6 and how many are faster, slower or the same:
BTW, 2 of the faster ones, my (Stuart's) upper and lower hutch lights are plugs that sit right below the C-8. But, at the same time, my Fibaro KeyFob is in that same room and only a couple of feet further away from the hub, but it is slower than before. So go figure.
One thing to note is that virtually all of my devices are in metal boxes, that I can't change, as I live in a condo, but some aren't, such as the free standing Fibaro Key Fob and the Palm Room Table Lamp Plug. While the devices connecting at 100, 40, and 9.6 varies from day to day, on only 1 day since mid-April when I installed the C-8 did I see any improvement over the C-7. Below is my slower/faster devices as of this morning.
I'm now thinking of trying one of the other two antennas on that page. I didn't get the real big ones at first as I'm not really sure I have a good way to mount them, so I was thinking of trying the smaller one first. This one:

vs. this one:

As I've also read that sometimes the lesser powered ones can perform better. But, before I pull the trigger on either of those I'd like your opinion on whether you think I should try to go with the bigger or smaller one, or if it even matters at this point.
Any ideas why I'm getting consistently worse performance from the C-8 vs. the C-7?
