Currently hard to decide, because the new fx-880BTG. Check the topic here: https://www.hpmuseum.org/forum/thread-18932.html

BTW the CASIO fx-991CEX is an EX added a periodic table and few more functions but no English or you can choose japanese version (JP-900) with English language available or if you do not need periodic table, the German 991DEX is a good solution, without English but lots of additional features packed.

Dig CASIO support page and use classpad.net for all emulators free.

All of these have more functionality than a "normal" 991EX.

FYI the fx-92+ Spéciale Collége is a French version and programmable (the only programmable Classwiz).
