I am biased.
I like the 8031 family.
I have written pre-emptive multitasking systems for it,
as well as state-machine round robin systems.
In assembler.
Who needs tools if you have a half decent macro assembler?
And if the macro assembler is not up to much, then you write your own pre 
processor using python.

The 803x bit handling is, in my arrogant opinion, still the best of any 
processor. - jump if bit set then clear as an atomic instruction rocks.


Where do you get such nice projects to work on?
