I think 46-50 will be about optimum at the viewing distance we use. One thing about going really large for close viewing distances, is that non-HD stuff starts to look very blocky. Untill everything is at least 1080, I probably wouldn't go about 50" - obviously it depends on viewing distance though.
I can't help thinking it's about 2/3 years too early to buy a 4k TV. I agree there's not much content, I suspect quality will improve even more as the technology matures, and they'll definitely come down in price significantly. There's still an early-adopter-premium to pay, compared with regular HD sets having pretty much leveled off.
I'll probably pick up something similar to the ones you're suggesting, and go 4k next time.
I'm a fan of Samsung, but different makes seem to have different "looks" in terms of picture quality. What I would say though, is once you turn off most of the processing, and tone down the colours etc, you can get a much better/more natural picture from any of them.
