Who should opt for the Sony a7R III?
With such a huge list of shared features between the two cameras, the a7R III advantages list is unsurprsingly short. While many will appreciate the a7R III's higher resolution viewfinder and LCD panel, undoubtedly the most important difference between the two cameras is sensor resolution. The difference between 42.4 and 24.2 MP is substantial. If you're shooting subjects where resolving small details is a primary concern, or otherwise want the ability to heavily crop photos for better framing (or to extend the reach of a not-long-enough telephoto lens), then Sony a7R III's higher resolution sensor will be worth the incremental investment over the a7 III.
Who should opt for the Sony a7 III?
If you've been on the fence about investing in a Sony mirrorless camera and you don't need the massive resolution of the a7R III or the blazingly fast frame rate of the a9, then the Sony a7 III has your name on it. It may be positioned in the lineup as Sony's entry-level full-frame camera, but the only indication of the a7 III's entry-level status is its price tag. The a7 III's comprehensive assortment of advanced features will make it right at home in many pro, advanced hobbyist or weekend warror kits as a primary or backup camera. For what you get, the Sony a7 III is a bargain.
