Which BASIC pocket computers make the best calculators?

[Hlib]

So, one of the best scientific calculators ( FX-9860GII) also includes the best mathematical BASIC computer as an application. And this BASIC computer from Sentaro21 includes the best calculator among old pocket and desktop computers :-))). Something like that.
Even in double-precision mode, programs in this calculator run twice as fast as in SysRPL.
Let Tim Wessman once again tell me a beautiful story about the hp-39gii. This calculator failed to translate the concept of a programming language into a flash application. What happened - is the biggest failure in HP`s products. However, this is still being bought by someone.
