Does using Electric stove vs Gas stove have any difference in food taste?
The simple answer is: no, heat is heat, it should taste the same. 

Reality is slightly more complicated than that. In reality, a cook learns how to cook well by instinct with his stove. When he changes to a stove with a different behavior, his instinct is suddenly wrong, but he probably does not know it. So he cooks as usual. But because the stove works differently, he should have changed the setting and time he uses. So, a stove change alone can cause food to taste worse - not because the stove is worse, but because the cook's skill is lacking. 

Also, an electric stove (especially an old fashioned one with iron hobs) cannot do some things a gas stove can, such as a very quick change in temperature. If the food absolutely requires this, it can turn out worse on the electric stove. But a good cook should be able to work around that. 

So, the more complete statement should be: There is no difference in taste between cooking on electric or gas stove, if the cook knows how to compensate for the difference in heating speed.
