Gas stoves will not be easier to clean than a glass-top electric, but otherwise are far better to use. The biggest problem I have seen with electric is that the burner does not stop heating when turned off- one needs to move whatever is cooking off the burner. In theory, temperature control should be ok, but I have never seen an electric burner that was as easy to adjust as a gas one.
Propane should be similar to the NG that I am used to- just have to be sure the burners are set up for propane.
I will presume you do not want to go with coal or wood....
