I have a friend who spends every his vacations in Abkhazia and don't want to go somewhere else. Also my mom was there a couple of years ago (in 2009, a year after Ossetian war) and she tells that Abkhazia is beautiful, but some infrastructure is still not rebuilt after 1993 war. On the other hand, South Ossetia is a tiny mafia enclave, I would not recommend to go there.
