I've had Vizio in years prior, little complains with them. Some died, some lasted (and as I said, under warranty, all's good).
Usually Vizio provided a lot of bang for the buck in years past, but prices in general have come down considerably, so if something like Samsung is available, I'd go with that.
I do have the Vizio sound bar for my main TV, and for the investment, I'm happy with it.
