As an observation: the He 178 was powered by the HeS 3- with a centrifugal compressor.The He 280 , flying before the E28/39, was powered by two HeS 8 engines, which, at that stage, had purely centrifugal compressors.
In fairness centrifugal, axial, centrifugal/axial compressors and even ducted fans were initially developed around the Heinkel team and Ohain was keen to move to axial compressors post the HeS3 , one of the several arguments being the potential lower frontal area of the axially compressed jet engine.
I would agree that Longer ron is quite correct in his qualified overall assessment though.
However do note that when you look at the long thin turboprop nacelles as on Viscount, F27, Herald , Hs 748 et.al , you are looking at housings for Rolls Royce Darts:
centrifugally compressed engines.
