I prefer keeping both on my chart, but generally, I have seen it respecting MAs more than EMAs, scientifically EMAs make more sense to me but on charts, you will always see MAs getting much more respect than EMAs. I am talking especially about the longer time frame candles, like the daily or the 4h candles, shorter candles can be dynamic, sometimes you will see them respecting MAs other time you will see them respecting EMAs, but in shorter time frames both these things don't have a lot of difference, so I just create a sort of range and try to keep that range as my Moving average because ultimately you are not sure which point it will bounce back from.
