Condition is everything. You probably had a faulty or malfunctioning Rolleiflex.
I have several TLRs, with the following 4 in heavy rotation: an Autocord, two xenar Rolleicords, a Rolleiflex 3.5F Planar. All CLAd with lenses in mint condition. The 3.5 F was entirely rebuilt by the Rolleiflex guru, Magicflex.
My Autocord takes pictures that are indistinguishable from those of my Rolleicord Va and Vb (not better, not worse: indistinguishable) and my 6-element Planar 3.5F at f/11 or smaller.
However, f/5.6-f/8, the fully CLAd Rolleiflex is noticeably different (some would say 'sharper'? 'better'? I'll go with different) than the Rolleicords and the Autocord. At 3.5, my 3.5F is a world away from the Autocord and Rolleicords.
I'm not dissing the Autocord/Rolleicords: in fact my Va is my favourite camera of all times: light as a feather, amazing lens, robust and quiet.
Also, regarding the Autocord - as much as I love mine, I've taken some of my all time favourite pictures with it - is much, much more fragile than the Rolleiflex.
I know people really want to love their Autocords, but a well calibrated 3.5 Planar/Xenotar is something else.
