Features such as voice control and smart home integration can be found on both platforms. However, due to its Apple interfaces, the LG offers you a little more connectivity options in this category.
If you prefer DTSMulti-channel-sound-system (Surround Sound) competing with Dolby Digital:X or want to keep this option open, the Samsung will leave you empty-handed. Although the G3 does not provide direct output of this codec via its speakers, it can forward the format to compatible home cinema systems and soundbars.
On the other hand, you will find a better solution for cable management with the S95C and the One Connect Box that comes with it. The flat connection box can be placed freely around the TV and allows easy access to the interfaces.
