I've had only good experiences on Ukraine Airlines, but as you say, who knows what the situation in Ukraine will be in a year's time? Do you have to book now?
I usually use Turkish for travel to Georgia and Central Asia, as it offers the most options and flexibility if things go wrong or have to be changed for some reason.
If you do book on Ukraine and take out insurance, make sure it covers war and civil insurrection - many policies specifically exclude these.
