And the Armenians are great for dealing with the Mongol Horse Archers - sooner or later they catch up with them and then it is a massacre. Finally, Georgia is close to your production centers and replenishing you army there should be easy, compared to having to cross the steppes to get to Volga Bulgaria.
Georgia is easily the best province to take on the Mongols. The problem is that if it does fall, they will begin expanding into trebizond and armenia. If you have valuable buildings there such as a grand mosque, this is not what you want. Another possibility is that the Mongols emerge in Armenia as well as Khazar. If this happens and you've no suitable garrison there to face them, you will probably lose your core provinces, unless you can get troops into that landlocked region asap. It can be a nightmare to stop the Mongols once they gain a foothold in asia minor.
