I have been to many resorts worlwide and clearly there are many better resorts than Erciyes in the Alps but we should not compare apples to oranges. Erciyes is the newest and largest resort in Turkey. It may not have the steepest slopes (in my view Erzurum ejder has this) or the best scenery (like sarıkamış with pine trees) but it is the most modern and best organized.

Pros:
-modern and fast lifts
-over 50 kms of pistes spread to four entry points with 13 lifts
-good combination of reds and blues and minimal waiting time for the harder reds
-reasonable off-piste options preferably with a guide
-10 euro ski lift price every day
-kayseri cuisine delicious and very affordable
-pistes accessible by 30 mins drive from airport and 20 mins from city center
-best mountain road (more like a highway)
-choice to remain in modern or affordable city hotels or more luxurious mountain hotels
-other options for non-skiers such as visiting amazing Cappadocia

Cons:
-can get windy and foggy so best to check for weather
-no trees, volcanic mountain
-very limited or expensive apres-ski, limited to a few mountain hotels
-no beautiful village but a modern city
-alcohol served only in hotels and hotel restaurants or can be bought from supermarkets for consumption at home
-beginner slopes get too busy so best for intermediates
-no black pistes

Although I am Turkish, I think I gave an objective review. For people like us to choose which day to travel, it is the best resort in Turkey. For tourists, it could be a nice diversion for a couple of days especially when visiting Cappadocia in winter.
