Art_Of_camelot, I would say slightly inferior to the TI-82, same would go for the FX-9750G. CFX-9850G is slightly better than 9750G because despite not having financial functions, it has color and 4 KB more RAM. However both models are inferior to the TI-82/83 because they are slower, both processor-wise and BASIC-wise and the calc hardware needs to be modified I think to support ASM, unless I am wrong. Seeing how only one person ever released ASM programs for the CFX-9850G I guess it is true. I would need to confirm this on casio forums, though.
As for the Algebra FX 1.0 and 2.0, they are superior to the TI-83+ but by far inferior to the TI-83+SE. It has around 700 KB of flash memory, ASM support and I think C too. It also have better LCD than these TI models, given that most ASM games are grayscale. However something makes them by far worse than the SE and would make them worse than the regular 83+ too if it wasn't for the large amount of flash memory: First, the BASIC language on them is slow and I even heard that it was slower than the color models. Secondly, the Flash memory on these calcs has a short lifetime. I believe it's the same flash memory than on the recent TI models. On TI models after about 200000 flash memory rewrites (Garbage Collect/Defragmenting), it stops working, which means if heavily used a 83+ calc would last about 20 years. However the AFX flash memory apparently lasts about 3 years if it is heavily used so the calc stops working afterward. Idk if it's true and if it's just caused by some calcs flash memory being defect, I got this info from Wikipedia and another site about all casio models.
The Classpad is the TI-Nspire of the Casio calcs, but better. Like TI, when it came out it had no ASM support, only BASIC. However it is better because it has a touchscreen, even if no native grayscale support, the BASIC language is MUCH more efficient than the Nspire, even though it's a typical calc BASIC language as you know it, and unlike TI, they quickly responded to the complaints by releasing a C compiler and allowing ASM programs to be run on the classpad by releasing new OSes. However one downside is that the latest OS is very buggy and Casio hasn't addressed the current bugs involving wrong calculations. I would say it's much better than the Nspire in its current state, even if much less RAM, but it is not as good as a Voyage 200.
The Casio FX-9860G is their most recent calcs. It's the best of all Casios. It is much better than the TI-86 in term of processor speed (altough I didn't tried the BASIC language to see if it's much faster than older calcs), it has 32 KB less user RAM, but one model has 700+ KB of Flash memory and the two others has 1.5 MB. It also has more features than the 9750G/CFX models and looks similar. Also like the TI-89 the Insert mode while typing stuff is enabled by default so it makes the shitty Casio PRGM editor easier to use. One of the 3 models (idk if it's still in production though) has SD card support and another one looks like a pocket electronic dictionary and is easier to carry in your pocket.
To be honest TI calcs are easier to use though. Despite the Casio having a menu system similar to the TI-85/86 it is harder to find the functions you want and the PRGM editor is annoying to use because linebreaks are counted as tokens and anything you type overwrites them, meaning you accidentally erase code on the next line most of the time
