Currently when looking for a full-frame mirrorless camera in the 2K-4K €/$ price range, the competition is among these models: the Sony A7III and its more expensive sister Sony A7RIII, recent Canon EOS R and new Nikon Z6 and pricier Nikon Z7 models. See our overviews of new Canon system in this article and of Nikon in this article.
We will compare here the characteristics of all of these cameras in a side-by-side table so that it is easier to pick up which is the best for anyone's need.
In the following table, only the differences among these models are reported, leaving out characteristics that are available in all models and secondary features.
First three models are around the 2500 €/$ (VAT included) price range, while Sony A7RIII and Nikon Z7 are in a more expensive range of 3500-4000 €/$ range.
[2-Dec-18] For missing data in the table: DxOMarks does not yet have measured performance of new Nikon and Canon sensors and DPReview has not rated Nikon Z6. This table will be updated when these data will be made available.
Values for a characteristic that are below average or worst are maked in red, while above average are marked in green.

Some quick suggestions:
- for action/sport shooting, the best features/price ratio is for Sony A7III.
- For video, Canon is the worst, it suffers from strong crop factor at 4K, missing high frame rates at Full HD and missing sensor stabilization. Nikon Z6 is very good for video (and quite better than Nikon Z7), Sony A7III is also very good.
- Nikon(s) and Canon models, being the first full-frame mirrorless models with the new mount, start with very few native lenses that can fully exploit new system capabilities, so maybe they are not yet the best choice if starting now from scratch.
