Describing something as being the best can be a little subjective. If you're a fan of a particular brand, that can impact your judgment. If you have had good experience with products from your early years, you will likely recommend the brand you're familiar with. The same goes for those trying to find the best TV.
One of the most important things to look out for when choosing a consumer device like a TV set is to look at your budget. The more you're willing to spend, the more you will likely get with regards to features and size. Most manufacturers offer similar products, with size and the number of ports determining the price tag.
