Can't say much because I haven't owned either one of those brands. A while back I had an EONON deck for my 2007 Camry and I wasn't too pleased with it. Very poor performance and these look very similar to those. I have heard that the Erisin is no different at least from some friends who used to have it.
If your choice is limited to those two, then my edge would go towards Ottonavi. If you are willing to forgo the stock look a double din unit, such as pioneer, alpine or kenwood with a metra kit may be the best choice in terms of quality and reliability
Good hunting
