As far as Fighting types go, I like them, but they just aren't as good. Machamp is obviously the best (at least I think he pwns), and the Hitmon duo are behind him. Right behind the Hitmons (or maybe even before them) is Poliwrath, and then Primeape. However, if you want a Fighting, stick with Machamp. I mean, he has four freaking arms!
In RBY Exeggutor was a staple. One of the best leads in the game since he had the ability to Sleep Powder the opponent's lead and then Explode on whatever switched in after. The fact that he had a ground resist in a Metagame where Golem and Rhydon were on EVERY FREAKING TEAM is a big plus too. :]
