I guess the question is "best" for what - speed, power, correctness, ease of use, etc.
For power and ease of use, I'd have to say the HP-200LX. It has a full, if small, keyboard for entering the equations. Multiline screen for editing. Can save/load equations. Easy to transfer to a pc for editing large complicated equation. Full L() and G() implication. Can do graphs. Can be used in a 1-2-3 worksheet.
In the calculator realm, I'd have to go with the HP-19BII. Multiline display, the full keyboard helps on entering equations.
Second on the calculator side would be the HP-17BII. Mainly for the pocket size.
The above is order I would develop a complicated formula - I'd start with the HP-200LX or the PC emulator of it. Debug it there. Then type into the HP-19BII. Ensure it works there. And, if I need smaller form factor, enter the final debuged complicated equation into the HP-17BII.
As far as I know the solver is the same on all three of these. The HP-200LX, of course, has some additional features.
I can't comment on any of the newer calculator, since I don't have any of them.
