TV plus Apple TV.
Costs a bit more, but is & will be definitive.
Be back bump
Absolutely. It's not even a close call.
"Smart" TVs are a gimmick and a poor value. They cost more--typically well more than the combined cost of a "dumb" TV plus a separate streaming box. The built-in software is uniformly inferior to the dedicated streaming boxes and is seldom if ever updated, meaning that a year or two from now your "Smart" TV will be looking sadly dated while the streaming boxes will be running the latest software and apps. This is because the TV manufacturers have zero incentive to add value to last year's model--they want you to buy this year's model.
As others have pointed out, having a separate streaming box also allows you to replace it or move it to another TV easily as needed.
It's a matter of personal taste as to which streaming box to choose. I have both the Apple TV and the Roku and between the two probably use the Apple TV 90% of the time, however both are good boxes. The Roku advantage is that it has a wider selection of "channels", however given the new App store on the latest Apple TV that situation is likely to change. The main service currently unavailable on Apple TV is Amazon Instant Video, so if that's important to you then Roku is currently the way to go. The other major streaming services (Netflix, HBO Go, Showtime, Hulu, etc.) are all available on both.
