I corrected my comment above. I entered the wrong command that had the wrong parameter: IW2 that I had tested. I use IW.
SARSEN works using the same file after unzipping. There may be an issue with my environment that is causing the zipped file to error.
FYI: SARSEN results are ~identical geometrically and similar radiometrically compared to S1TBX and GAMMA. SARSEN is about 3x more CPU for GTC, and 10x more for RTC, than S1TBX.

@S0sh0rt the not well-formed error comes from ElementTree and it hints that the manifest file is not a valid XML. It looks like a corrupt zip, or the file is really badly broken for other reasons.
Not a Sarsen issue. I'll close.
BTW: GRD images have the IW/VV group, not the IW2/VV one.

@S0sh0rt thanks for doing comparative testing, I didn't in fact check s1tbx yet!
A question: with "3x" do you mean 3x slower?
