I've had the a7R IV (not the A revision) since launch and haven't experienced an SD Card slot failure as yet. In terms of layout they are very similar just a couple of minor differences like you mention with the record button and C1 buttons switching places. The a7R IV is also missing the dual top dial that lets you choose between still, movies and S&Q mode which also changes your exposure settings if setup. On the a7R IV these are all on the same dial and what you have set for stills is the same for movies (always frustrating!). The menus are very different but like Tony said you can program a lot into the My Menu and customize it so that you rarely need to enter the menus.
