Thoughts? Erisin 3090A - Single Din, quad core, 4.4, 1024x600

I'm looking to get a single DIN flip screen style head unit. Looks like there are really only 2 quad core options out there:

1. Eonon GA1312: Seems to be relatively popular Klyde design and shows up under a few other "brand" names. It meets my needs but the basic downsides here being the 800x480 screen and typical lack of an external microphone. From a Youtube walk through it looks like it is a KLD5 MCU.
   
   
2. Erisin 3090A: This looks like an upgraded quad core version of the Erisin 8990A (dual core system). This unit has the upsides of a 1024x600 screen, an external microphone (important given this is going in a loud sports car), options for DAB radio and DVB-T TV (not useful here in the US), and a removable face plate. (I can't post links but the specs are posted at the first google search link for "ES3090A")

Needless to say the Erisin looks like the better on paper, but I'm hesitant to pull the trigger. Anyone have any experience, thoughts, or comments on this unit?
