I've done extensive research on getting a new box since I was unhappy with my current Pelican System Selector. I mostly wanted one with more digital audio connections and remote capabilities (I have the original selector without the remote).
I've heard good things about the Psyclone and the older model Joytech. This new Joytech looks pretty nice, so I'm now considering that, but more people have recommended the Psyclone than the older Joytech.
I personally didn't see any issues with image loss with the Pelican Selector, but admittedly I only used it very sparingly with 720p picture. The majority of the images pumped through it were 480i and 480p. And the 720p was from a few Xbox 1 games that supported it, not my 360 (Which I kept connected to the free input on my TV.)
They've raised the price of the Psyclone at Best Buy to $120, which has delayed my purchase for a while in the hopes of a deal.
