What is Reddit's opinion of Casio scientific calculator FX-JP900-N high-definition Japanese display function and function more than 700?

From 3.5 billion Reddit comments

It's partly because I'd like to be able to just pick one up from the store at a very inexpensive price that does everything my fx-115 es plus does. I have more-powerful graphing calculators, but would like a cheap one I can take everywhere without worrying about having it stolen or broken, as well as having a longer battery life than any graphing calculator has. The much faster (according to benchmarks) and aesthetically more-pleasing fx-991ex would have filled that need for me. The aesthetics matter in this case since I can easily see more information on the screen at once and have to scroll less often if at all in order to see a longer formula. However, the 991EX (US) lacks lots of functions that made its predecessors of 6 or 7 years here stand out. I know for certain that the Japanese version has even more functions (by a small margin) than the German version and can be switched to English, but it would be three times as expensive for me to acquire as well as requiring wait time for it to arrive. The whole point was to be able to find a calculator that can easily be replaced that I can take everywhere that is at least as good as the one I have with an updated processor for more-quickly making intensive calculations and that's even easier to use due to a display that can contain more information.

Note: Just to confirm that the ClassWiz series is significantly faster than what I have, I watched this video and performed the same calculation on my fx-115ES Plus. While my 115ES Plus, at 2 minutes 58 seconds, was 30 seconds faster than the 991ES, it was vastly outperformed by the 991DEX, which only took 36.8 seconds in total. The ClassWiz series, it seems, is about 5 times faster than what I have according to that example.
