These are some Pokemon that you should consider using instead of the ones you asked about.
Roserade has higher special attack than either of Drapion's attack stats and can learn sleep powder and leaf storm, which makes it much better at forcing switches and setting toxic spikes. It also learns spikes.
Lucario has a lot more resistances and a higher speed stat compared to Gallade. It learns extreme speed, which is deadly when combined with swords dance.
Gliscor has better offensive typing and higher defense stats and speed than Honchkrow, and it learns ice fang. This makes it better at being both a tank and a sweeper.
Azelf has higher speed than Gallade and can learn explosion, stealth rock, U-turn, and several powerful coverage moves. This makes it better as both a dedicated lead and a sweeper.
Compared to other fighting Pokemon, Gallade learns more moves but has less speed and worse other type. You should use it only if you really want a fighting Pokemon with shadow sneak, leaf blade, will-o-wisp, or trick. As far as I know, Honchkrow and Drapion don't have a niche.
