My favourites are easily counted: HP-48GX, HP-41, HP-42S, HP-11C, HP-33E;-)
I'm still developing for the HP-48 (SpeedUI,..)
and HP-41 (INIT module for CY, CCD OS/X, other specialized ROM modules)
The HP that convinced me to enter the 'RPN side of life' was the 33E
of a friend,
which he gave me for a few days, and of which I worked through the whole manual.
After that, I was kinda hypnotized by the RPN entry principle!
The HP-41C and the HP-11C were my first two real calcs, the 11C being small,
robust and relatively modern compared to the LED calcs like the 30 or 60 series,
but too limited regarding programming features.
So the 41 was my favourite for many years.
There also was a great user community for the HP-41,
partly organized in clubs like the CCD and PPC.
I was introduced to Saturn assembly with the HP-71B and the Forth/Assembler ROM.
Very powerful machine, but IMHO not very practicable due to the one-line display.
And then the HP-48 came out:-)
Still my favourite programming platform, and the last *real* HP Corvallis RPN/RPL calculator,
with an ENTER bar where it belongs, and rock-solid hardware and OS software.
