Absolutely the right recommendation, IMO. My RX100mk3 is a great camera for what it is: Small, portable and fine IQ (though I'll soon replace it with the mk4). But it has one huge limit as a travel camera: Focal range is 24-70 mm, not long enough for *my* main travel camera.a6K=24 MP APS-C sensor, and outstanding AF system. Even with kit lens it will give you much more latitude in most (if not all) situations (and if not, Sony has some reasonably priced fast primes). The question is what are the images used for.But how do you find the image quality between the A6000 + kit lens and the RX100 IV? I have a brand new A6000 in front of me but I'm thinking about returning it back and take a RX100 IV. 4K is not really important to me. What it is important is the image quality and the portability as this will be a travel camera. I'd prefer not to "show off" my camera (A6000+lenses) every time I go out. And between those two, the camera that will allow me to put it in the pocket is the RX100 IV.
Portability favors the RX100 hands down but you are paying a very high premium for it (and a lot of it is for the 4K that you don't really care for)!
Tough question to answer because I don't know your shooting style and subjects but if 4K is not important to you and superior stills is all you care about, go for the a6K. If you really like it, the road to upgrading to more expensive lens is open (16-70 CZ f4) and these lens will keep going with you as you change bodies. I wanted a carry everywhere camera, it will not replace my a6K that I use with 10-18, 16-70, 70-200, 70-400. To me, the RX100 is the second camera (that is likely to be used more often than the primary one)
Bottom line: get the a6K
My A6000 is not as small by any means, but has great IQ and AF, and I can easily get out to 300 mm with it (18-200 lens), so it is much more flexible for travel. And it's not as large as a DSLR
