Assuming all are fit to you, the Red Vitus, as it looks too small. But in eyeballing the images it is interesting that the black Vitus appears smaller than the Red one, top tube different length?

Sell the Red Vitus as a frameset, box the parts. Perhaps Nashbar still has one of the 58cm NOS Vitus frames you could purchase for the future.

Selling prior to Christmas is dangerous, folk are thinking gift shopping, your spouse could even expect the funds from a sale to be put toward a downpayment on her gift.
