Not sure I'd call it eclectic. Abstruse, maybe. (My problem with the UI is that I have problems with combinations, e.g., forcing connections in LAX and LHR and forcing AA operated flight between LAX and LHR but allowing BA and IB for others -- it usually barfs or tells me there are no flights.) That said, I do use it to price all-in fares, since EF usually gives the pre-tax&tip amount.

Given my experience in booking AA codes, I wouldn't trust ITA if it told me it was fine, absent direct or credible reports of actually being able to book it.
