I remember a magazine from 1995 where they compared loads of programming languages and interviewed some games developers to see waht they used (Rowan Software, Bullfrog, Argonaut and Revolution).
Here Ive just found it. PC FORMAT, issue 44, May 95.
They compared 8 languages and rated them:
MS Visual BASIC 3.0: 90%
MS Visual C++: 80%
Borland C++ 4.5: 86%
Borland Turbo Pascal for Windows: 82%
Borland Delphi (which had just come out): 85%
Borland Turbo Assembler: 76%
GFA Basic for Windows: 75%

): 64%
Rowan Software's current 3d engine at the time was Assembly, as was their language of choice. They planned to changee over to C in 96.
Bullfrog used C and a small amount of assembly. They planned to change over to C++.
Argonaut Software used Watcom C++, when programming for Windows they used MS Visual C++.
Revolution used C, then converted time critical routines to assembly.
