Hello mate, nice to hear from you again.. The SPECTRA system is combat proven and considered more mature than Eurofighters Dass.
Hiya Duplex!! Nice to hear from you and thanks for the welcome back.
There was an ex in the last 2-3 years between RAF and the French, Typhoons V Rafale, all the BS aside the RAF crews did say that SPECTRA was "effective", whether that means it thwarted their simulated attacks remains to be discovered but it seemed to have given DASS and CAPTOR some problems.
