Would I had to choose from that list I would have selected Altagon. Same suckieness factor as Agilent.
Its obvious those medical/lab division is making the real money and probably feeding the whole company, hence keeping the Agilent name, while T&M division got sour and kicked out and separated, and will have to start all over again to establish the brand name from the scratch.
Like above B@W examples: Altogon, Vectelo, Altagon , its obvious these sound so Western, compared to Keysight, Sightshift, Stormkey, Boldsight, Keyhawk, Boldfire, to me these sound or taste more friendlier to "Oriental" ears ?
A preparation to attract potential Chinese buyers ?
Edit : Another thought, what happened to T&M market if Danaher bought this Keysight ?
