I have an Autocord and two Rolleicords (one Va and one Vb). They are my most used cameras (though I have other TLRs). They are both extraordinary cameras IF in the right condition. A couple of points from me:
1) With all these cameras, condition trumps make/model, by a country mile. Buy the one that is in the better condition THEN send it to a qualified technician for a once-over. My Rolleicord Vb was close to unused but had sat in a cabinet for 50 years. Only after a CLA it was really able to show me what it could do.
2) Remember that many people will purchase these cameras, then attempt to 'fix' them or 'CLA' them, only to then dump any botched attempts on the bay. Sometimes they will mix and match bits and pieces from different units just because. You WILL find a lot of garbage TLRs on ebay, even when they're sold as 'near mint'. Do your research before buying. Buy locally, investigate the history of the camera.
3) Minolta Autocords: remember that Autocords are in general cheaper and more widely available than Rolleicords in the US ---> a significant number of native English speakers on this and other English speaking forums is in the US ---> more people in the US will have had access to an Autocord than to a Rolleicord over the past decades ---> spot the selection bias wrt Autocords recommendation
4) Opposite bias in Europe, where the Autocord is rarer than the Rolleicords (except in the UK).
5) You will hear/read something to the sound of 'Autocords are way sharper than Rolleicords/Rolleiflex/<insert cameras>' no they're not. My Autocord is a fantastic camera, it's super sharp, but I wouldn't be able to reliably select its output rather than the Rolleicord's in a blind test, and neither would you. They're just as sharp, they're both in mint condition, they focus well, the focus is calibrated etc. Actually, my Rolleiflex 3.5F III with a 5 element Planar, completely and fully restored by Magicflex, one of the best Rolleiflex repairmen in the world, is noticeably sharper than the Rokkor in my Autocord (also in mint condition, fully CLAd by Karl Bryant in the US) from f/3.5 to f/5.6. f/11 and above they're all the same - if they're not, there's something really, really wrong in one of the cameras.
6) My Rolleicord Va is significantly lighter than my Autocord. It's so light that I can cycle for 2 hours with my Rolleicord hanging from my neck and not feel it at all. The Autocord is lighter than my Rolleiflex.
7) My Autocord is (for me) easier/more natural to focus than my Rolleicord.
So it's not black/white.
