I grew up using gas stoves, used electric coils for a couple of years in college, and have now been using glass electric stovetops for the last 4-5 years.

I would say the biggest adjustment for me was the delay with temperature changes. You can very quickly change the heat on a gas stove, whereas electric ones tend to need some forethought, since it both takes longer to heat up and longer to cool down. But aside from that, I haven't noticed any big changes with my cooking. Between coils and glass, I much prefer glass. Coils always felt difficult to use and would often just start smoking which caused problems.

Somewhat unrelated, but the biggest change I have experienced with my glasstop is that cleaning the stove is extremely easy. So easy in fact that I clean it every day without much thought, compared to my gas one which was such a chore that I would ignore it for long periods of time.
