I have Sony A6000, you can visit my flickr photos and you will see I use a combination of Sony A6000, Sony A7 and NEX 5N. I still shoot Pentax K-5. My usage is most on the aps-c with Sony A6000. It is lightweight and compact. The wonderful lens on the camera will make a lot of difference. The high end lenses series in the G or Zeiss branded lenses of Sony native E mount are expensive. I highly recommend the non-native Sigma (especially the older version1) on 19 mm f/2.8 and 30mm f/2.8. The Sigma 60mm is only available in version 2 and the 60 is the sharpest aps-c lens for Sony that I have used. Well worth the money and you can shoot all wide open and not worry about sharpness. That is especially true on the Sigma 30 and 60.

The Sigma 19mm f/2.8 is the weakest link out of the trio but I like it for landscape and street shooting. It is my DA 21mm replacement on Sony aps-c sensor camera Sony NEX 5N and Sigma 19mm f/2.8
Sigma 60 and NEX 5N
The A6000 is a fast and action packed camera. It has its quirks but it can shoot 10 frames per second and it has a Eye-AF where it places the focal point on one's eye and a green square can appear over one's eye for focusing when face detection is on. The A7r2 and A6300 even have Eye-AF and refined lock-on focusing in AF-C and video. Yes, all AF with work seamlessly on video.

If you like to experiment with MF lenses on the cheap or the opposite with Leica priced lens, you will be wowed on Sony with range-finder like lenses such as the Voiglander 40mm f/1.4 and Voiglander 21mm f/1.8
Voiglander 40mm f/1.4 on Sony A7 -- the combo is tiny, not any bigger than a 43mm f/1.9 on Pentax
Voiglander 40mm f/1.4 and Sony A7 likely in f/1.4
And you can reuse your super-takumar (my favorite Pentax MF lenses) on Sony A7 usage such as the Super-Tak 105mm f/2.8 (tiny m42 lens) on hiking
Sony A6000 and Super-Tak 105mm f/2.8 and lens turbo that adds 1 stop of light and provide a 0.71 crop factor to offset the 1.5 aps-c crop factor.
Can other mirrorless does what Sony has done, you bet! And I think both Olympus and Fuji have done amazing work on their latest. But Sony has done quite a remarkable job on the senor along with innovative products and the previous problems with lack of lenses are improving and not as bad as before. The big issue on A6000 or the development on aps-c in general lies in Sony putting more emphasis on FF instead of aps-c. It is both good and bad. Bad in customers like me who love aps-c and good for FF die-hard fans who are crazy on resolution or the bigger-the-better camp. When I get A6000 and A7, my take-away is that the smaller camera is more satisfactory for me. The FF is very much hyped up for my usage. FF is great but not as fantastic as what others have hyped up the value of FF for average-joe enthusiasts like me.
I am much happier with a lighter camera when I go hiking or carry my camera bag for outdoor activity. The FF does has its important places and it is worth the trouble and money. Had Pentax gotten K-1 in 2013, there is no way I will get Sony A7. If I go back in time and that Pentax has a solid K-1 in 2012/2013 time-frame, I will grab k-1 for professional work while getting A6000 for weekend and light camera to have with reasonable tracking, frame rate and reliable AF. The A6000 and the Sony E mount excels the most with adapters that you can easily buy a few AF native lenses while using many of your existing lenses with AF support (Canon) or shoot all in MF. Sony excel in focus peeking along with good magnified view on EVF or LCD. The EVF is superb and once you get over the hurtle in adaptation with Evf over Ovf, you can't go back as you see the aperture change and melt your hearts away with the bokeh and rendering effect of vignette right at you view finder.
