Digital trends has good comparison reviews up in YouTube looking at the h9f, tcl r617, Sony x950g. They agree that the h9f is a really good value. It isn't perfect with some clipping/crushing of highlights and blacks, and a fald algorithm that is a bit slow. That being said, I would think that it is better than the M series from Vizio. You get fewer zones and nits with the Vizio unless you go up to the p or px series. I don't think people would say that Vizio has super awesome uniformity or no dse. Likely typical for a TV in that price range. More would say you have to pay for the Samsung or Sony to get better uniformity. Also Vizio isn't known for its upscaling either. That is Sony's lunch.
Also the Vizio interface can be slow compared to a tcl Roku. Sony supposedly has a faster Android interface than Hisense.
