iPad Pro 11 ”is appealing in every way, and is presented as a huge step forward over previous iPads. It is not. Essentially, this is last year's iPad in a new design, with a more powerful professor, but too many compromises. The vast majority should buy 10.5 ”iPad Pro, and afterwards I wish I did it too.
If you use multiple processor cores to export 4K video daily or process RAW images, the iPad Pro 11 is the best choice. Otherwise not. There is no other advantage, in practice. But many drawbacks.
I chose Pro 11 "over 10.5" mainly for the following reasons: larger screen, thinner edges, FaceID, larger keyboard (onscreen). All the reasons fall away in practice.
Larger screen: The difference is about 15%, but iOS does not use the extra surface particularly well. At the same time, the screen begins to become so large that it is uncomfortable for the eyes. Around 11 ”, the distance from the eyes should be around half a meter, but you usually keep the iPad closer. This format works best with the iPad on a table, with an external keyboard.
Thinner edges: It looks nice. It gives a little more space in height. But on the width, the space is actually smaller because "edge to edge" is pure lie. The distance to the edge is smaller on one width but thus larger on other width than Pro 10.5 ”. A less pleasant consequence is that it is very easy to accidentally get input from other things because the touch surface goes further down, for example if you rest iPad against the stomach, knee or the like.
FaceID: In theory, this would make it faster and easier than TouchID on Pro 10.5 ”. In practice, it makes almost nothing simpler or faster, but many things impossible or slower. The only way to unlock Pro 11 ”is to have your head quite straight in front of the iPad, which makes it impossible to quickly send a short answer to a message with the iPad lying on the table. If you want to do something quick, you either have to lean over the iPad or keep it up, which quickly becomes more than legally chewy. TouchID is quite simply objectively superior to unlocking the iPad.
Websites and apps were my big hope for FaceID because there TouchID is pretty awkward. If you juggle a dozen web pages with logins then you have to constantly change your mind to read the fingerprint. It's no better at Pro 11 ”, just different. It takes a little longer to log on to websites with FaceID, and you often have to change your grip anyway because the camera sits exactly where you easily hold your hand.
Bigger keyboard: This I looked forward to the most because I work with my iPad. Larger buttons should make writing easier. Unfortunately, the buttons are more often smaller than before before Apple has changed the layout and stowed several new keys instead. It is essentially harder to write on than iPad Pro 9.7 and and I would probably even say the worst onscreen keyboard Apple ever made for portrait mode / vertical.
In summary, one can say that in a niche use case, Pro 11 "is much better (really heavy applications plus using iPad on a table with external keyboard). However, most of what most people do ("iPad things") is worse than before. It is consistently in lots of little things, from that Pro 11 ”is much harder to pick up from one table to the new edges cut into the hands.
Total sum, a much more expensive and slightly inferior iPad relative to the price and its predecessor. Lowest price value in an iPad Pro ever, except for the extremely small percentage of users who sit all day and export video. Swallow the pride of having the very latest and buy 10.5 ”instead. Both are incredibly powerful and have almost identical cutting surface, but 10.5 ”is more ergonomic, economical and durable.
