I was just wondering if someone could explain to me the difference and/or similarities between Robotech and Super Dimencional Fortress Macross? Plot wise, character wise, story wise, animetion wise... anything that comes to mind...

I'm just wondering because i dont know if i should watch both or is one of them suficient? I'm currently thinking of watching Robotech only...

Thanks for any information and/or opinion that you might provide for the cause..
