Maybe cuz the minimum tick in ES is 0.25, which divided by 10 comes to 2.5 cents on the SPY, which makes the spread in futures higher than in the etf. Also with ES you have less strict margin requirements and can go as high as 1:10 leverage or above and can easily blow up and lose everything, while with the SPY you cannot go above 1:4 leverage if you are daytrading and 1:2 if you are position trading and you cannot lose moneyt as fast as with futures and also trading stocks helps you use a better money management.
To me a 5 min chart of SPY looks better than a 5 min chart of ES..The Es chart always looks a little "edgy" on the candles

Just my simple opinion though..
