Anything related to Morse without John Thaw is crud! It's like having Fawlty Towers without John Cleese or Columbo without Peter Falk.
As for Sherlock...
Rathbone was brilliant despite run of the mill scripts and one dimensional supporting actors. (you can dig up some of his old radio stuff here

Cumberbatch is brilliant because of the scripts which gives the supporting actors depth and backstories (you gotta love the concept of Mrs Hudson being the widow of a drug lord who drives a red Aston Martin 'Do you know what speed you were doing'..'Of course not I was on my phone')
Anyway..I'm a philistine and I kinda like Robert Downey Jr as Holmes in Guy Ritchies two films with Jude Law as Watson....and Jeremy Brett did a fair old job as did Clive Merrison and Michael Williams on the BBC radio series
