Štúr specifically based Slovak on Central slovak dialects because it was softer and more pleasant to all Slovak speakers, everyone basically agreed. Trnava dialect is too harsh ,and nobody from Western Slovakia could even understand eastern dialects. Also I think Moravian sounds better and more pleasent than Czech from prauge which sounds strange to my American ears. How do you go from pronouncing byt like bet. Moravian sounds like a Slovak speaking Czech, pleasent and nice.
Btw I just went to Košice for the first time this past weekend, really nice city I was thoroughly impressed.
