It was a truly awesome machine. When I left college (which had a B6700) and went to work on Honeywell and IBM machines it was like taking a long sad walk back to the dark ages.

One small example: the job control language (WFL) was an Algol variant which was great to program and Turing complete. Compare to IBM's appalling "JCL".

Array bounds checking with useful source level error messages (versus S0C4 abends and a core dump on IBM), writing multi-processor apps in Algol or COBOL was easy (versus close to rocket scientist level on an IBM requring for example that you code in assembler). Flags to distinguish code from data so data would not get executed etc etc.
