A very late answer, but I would say that if you want a 2.8 lens that is closest to the Xenar, get a 2.8 Tessar.

Unless you want the Planar/Xenotar lens, Ikoflex with Tessar is a good as a Rolleiflex and better than a Rolleicord. I have several of each. I would definitely prefer the Ikoflex over the Yashica and most of the other Japanese TLRs. My II has a Tessar and My IIa (second version) (built like a tank) has a coated Opton Tessar (No Xenars).

There are a lot more Leica models, therefore there are more to collect making each one more valuable. Also, I believe that with the collapsible lens and other gadgets, the Leicas are more fun to use.
