I've never been much of a fan of Electric type Pokemon. I've always found that they have rather limited movepools compared to the other types. That might just be my lack of experience with them, but I've yet to find an Electric type that I really like. Usually I find myself a Psychic type (or another Pokemon that can easily learn Electric type attacks) and teach it Thunderbolt.
I have, however, used both Electivire and Luxray at some point, but I suppose that when I've been playing Platinum that Magnezone has appeared on my team more often than the other two, so I'll have to choose Other this time around.
Ampharos found its way onto my team in SS multiple times, mostly because it's so easy to get in the early stages of the game, and right before a Flying type gym no less! Magneton and Lanturn appeared once or twice, but less so than Ampharos did. As I mentioned before though, a Kadabra with Thunderbolt was far more common than Ampharos ever was.
