Assembler can be fun.

 
Especially PDP-10 assembler. Wonderful instruction set.

 
Need to play around with -10 assembler sometime.* The -11 architecture
is also very nice (if more limited for Large Programs) - not hard to
see why a number of microprocessor designers took inspiration from it.

 
From what I've seen of the PDP-10, the VAX-11 instruction set
was superior.   I'm sure the PDP-10 folks will disagree, but
simply thinking about character handling on the PDP-10 gives one
a headache.
 
 

Au contraire. From what I remember from 50 years ago, The idea of defining
different-sized bytes is a real plus. Pity it was limited to word
boundaries, or it would have been actual BitBlt instructions. Several
machines use byte pointers in memory - Honeywell 6000 EIS instructions, and
I believe XDS Sigma. Quite flexible once you’re used to it.
