Nikon quality at the best price ...

Of all the "amateur reflex" range of Nikon (D3300, D5300, D7100) is undoubtedly the best deal: the image quality is potentially the same (same sensor) throughout the range. Other models - D5300, D7100 - offer options (swivel screen, GPS, etc.) that are billed dear ...
Similarly, you would be wrong to despise the little zoom this kit: to use, it is excellent, very effective stabilization and above it is almost given in this kit. Also note, compactness and low weight of the set.
In short, the quality / price of this kit is itself remarkable!

The image quality is comparable to that of high-end SLR brand (I could tell, because I also have a D800).

To sum up:
- You have a mobile phone or a compact: go for it without hesitation, you will see the difference.
- Looking for a quality / price ratio: take the entry-level model rather than the other
- You have goals and Nikon accessories and you want a second backup device not expensive: the D3300 is compatible with all recent Nikon lenses and flashes.
