I have a Zeiss Planar, two Zeiss Tessars, and a Schneider Xenar, all f/3.5s. The Planar is sharp and crisp, with somewhat high contrast. The Tessars and the Xenar are softer but equally crisp, with a sort of 'glow' in the mid-tones and a look I can only describe as the light wrapping itself around the subjects. It's a difficult one to describe, but I like this look, so I use my 'flex Ts and 'cord Vb more often than my 3.5E2 with the Planar.
The Ts and the Vb are also lighter cameras to carry, which at my age is a big plus. They can also be adapted to take 16 exposure kits, the Vb both 16 and a 24 kits. All four Rolleis take a 35mm exposure back, mine has a separate back so it probably dates to the 1940s, but it works. '35' in a Rollei is an odd size, but now and then it suits.
Without expanding this into a mini-book, I noted you already have a Rolleicord. My suggestion is that you go the economy way and either get your 'cord repaired or invest in a Vb. They are fine cameras in their own right and 95%-98% as good as the bigger Rolleis, with the advantage that they were amateur models and so not likely to have been used almost to extinction in pro studios.
Whatever your decision, I'm sure you will be a happy Rollei shooter for a long time to come.
