Technically superior in what way?  IIRC, CDMA provides better spectrum 
use, but GSM uses more bits for encoding the voice, which results in 
better audio quality.  However, it's been a while since I read the book 
on cell phone technology.  A strong signal doesn't get you much, if the 
audio quality is poor.  Also, coverage has nothing to do with 
technology.  That depends on where the carrier wants to spend their 
money.  Rogers and Bell also have the choice of two bands, which gives 
them more flexibility for coverage, than Telus, which has only the high 
band to work with (At least in this part of the country.  It may be 
different out west, where Telus was the principal phone company.  Rogers 
has both bands available across the entire country.).  The lower 800 MHz 
band tends to have better range than the 1900 MHz band.  This situation 
goes back to the days when there were only two carriers in each region, 
that shared the low band.  In Ontario & Quebec, it's Bell and Rogers.  
Out west it was Telus and Rogers.
