The Samsung H7150 LED TV is a very good TV with great picture quality. It has a glossier screen than the Samsung H6350, but reflects less light. It also has better screen uniformity.
Overall, the Samsung H7150 LED TV is a great TV and should not disappoint you. Choosing it over the H6350 is worth it if you want better uniformity and fewer (although more defined) reflections.
The Samsung H7150 is very thin and has small borders. The case is heavier and feels sturdier than the H6350.
At about 23°, the colors change and become whiter. You can still see the picture, but it isn't as great as directly in-axis. This isn't a deal breaker unless you always sit at an angle.
The H7150 has a glossy screen. It does a very good job of reducing the luminosity of the reflections. However, they are more defined than the semi-gloss finish on the H6350. If you have a light directly behind you, you will prefer the H6350, but if the lights are overhead or on the side, the H7150 reflects less ambient light, so the picture quality is better.
Samsung has the best selection of smart TV apps on the market. The web browser is also good, but heavy websites feel laggy on it. Check out our full review of Samsung's 2014 Smart TV platform.
