visually speaking I don't like the .gifs but that is because I have a brain injury and am sensitive to to that. I don't think either design holds any great advantage over the other but I do like the less is more approach. It might be nice to have links to internal general descriptions of each controller, but you may feel that would clutter up the index page.
My guess is that your links page will have external links to the controller sites but a quick overview on your site may have some benefit, particularly if you end up taking ad revenue like for accessory add-ons etc.
And to build an even better resource, perhaps integrated links to 3rd party accessories would be good too. For instance, when a particular controller shows available options, they could link to the controller product page, and when a controller accepts items like float switches, water sensors, etc. you could link to various 3rd party vendors of those items.
Although my decision might have been the same, I sure wish I knew about this comparison before I bought my unit. Is it OK for me to add you to the links on my web page?
