I think it's great that Apple decided to try larger screen sizes and offered 2 different options to boot. I agree, the 6 plus seems a little too large, especially with the larger bezels on it. Not to say its wrong. I think a lot of people would find it perfect. Personally, I like the design of the LG G3 because they reduced the bezel as much a possible with a large display giving the phone a smaller footprint than competing models with the same size screen. Just commenting on the phones physical design and not their particular implementation of the OS. Haven't tried the phone so can't comment on how it performs, though I am a fan of both IOS and Android.
With regard to the nationalism, regardless of where the brand originates, the phones are all assembled in China. With regard to hardware sales, a majority of the cost will go to where the materials are bought and where they are assembled. I personally think the point is moot. If you really want to keep money local, buy from small mom and pop shops that redistribute the wealth more evenly. Big mega corporations horde money: How much of a cash surplus does Apple have?
