What you learned is still true. Most of the outright bugs in the article you reference have been fixed. But the design problems are still there in both csh and tcsh. In particular, the problems with manipulating file descriptors to separate stdout from stderr are still there, the signal catching is not as clean as sh/bash, and csh/tcsh quoting is a mess compared to sh/bash. I know of no good reason to prefer csh/tcsh.
