Sony SLT-A65 or NEX-6

Hi everyone,
Indecisive... I'm still undecided!!!

I had a compact (Canon Ixus) and then super-zoom compact cameras (Panasonic FZ...).
It has now been several years that I hesitate to get into buying a reflex, after failing to find a device that really satisfies me (at least on paper and through testing). In fact, I am looking for a device that can give me the best possible quality during my excursions: I love the landscape photographs, macro shots with background blurs, capture the different shades of sky, night photos... And for that matter ($1500-2000) I would also like to have something that can make real (all time AF) movies.

So my short-listing was focused on the Sony range, especially on the Nex-6 and the SLT-A65: best actual EVF, great focus accuracy...
Here are my first impressions on these two devices I've tested a little bit in store:
SLT-A65
++ I love the handling and menu navigation (very intuitive, all the settings can be changed quickly)
++ From what I read, the Sony lens kit DT 16-50mm F2.8 SSM OSS is great (for a "cheap" lens)
- - The increase in mega-pixels is rather than qualitative (worse low light sensibility, sensor dynamic, bigger size of files than with 16MP...)

NEX-6
++ The near perfect sensor (dynamic, performance in low light ...)
- - The lower quality of the NEX lenses ?(the mitigated Sony 16-50 compact, no cheap zoom lens at F2.8)

When I was in the store I asked a seller for advices and he told me (quite logically) that these two devices were not intended for the same audience. And, as the compactness is not a primary criterion for me (I do not see myself lugging all days with the NEX in my pocket, especially if I have to carry 2-3 lenses continuously), I'd better take the DSLT, I would be less limited. Except that after the tests I've read, the NEX does not seem limited at all, quite the contrary.

I hope you do not get lost because I need your lights:
since on interchangeable lens cameras the lenses quality is as important as the body one,
should I take the SLT-A65 and its "worse" sensor but better optics (Sony 16-50 F2.8 SSM 18-135 F3.5-5.6, 35 F1.8 DT SAM...) or rather the NEX-6 with its best sensor but less good lenses (Sony 16-50 F3.5-5.6 OSS, 18-200 F3.5-6.3 OSS, 35 F1.8 OSS ...) ?

Is there other key parameters (features) that one but not the other would have?!?

Thank you for your opinions
(and sorry for my English level)!
