Sigh.  As long as it's possible to "get there from here", I don't 
much mind how an instruction set's laid out.  I'll learn it and learn 
to work around the problem areas, such as the lack of an inclusive-OR 
instruction on the CP1600, or the weird setup of the RCA COSMAC, or 
the asymnetry of <fill in the blank>'s instruction set, or the lack 
of a hardware stack on a PDP/8. 

If you want strange and asymnetric, try working with a few samples of 
the current crop of microcontrollers.  You can get used to anything.

In a way, this line of discussion reminds me of an Inuit criticizing 
the Tongan language for the lack in the vocabulary for different 
types of snow.  You work with what you've got.
