Competition between two mole-based Pokemon. Both are Ground-types (though Excadrill gains a second type), can learn similar moves that are standard of the type, one excels at Speed while the other does at Attack.
Which one is your favourite or you prefer over the other, be it for stats, design, usefulness, attachment or other reasons?
My vote has to be for Excadrill. It beats Dugtrio in almost every aspect. It looks cooler with the drills and all. It's part Steel-type, which makes it a bit less frail, plus the fact I'm fond of that typing. It cannot beat Dugtrio's Speed stat, but makes up with monstrous Attack and HP. And it looks far closer to the real-life mole than its fellow (then again we don't know how Dugtrio looks underground, but meh).
