Freedom and/or Strike Freedom is everyone's favourite, same goes for me too. Awesome firepower, super fast agility and stunning great design. Basically from the looks of it, anyone can tell it's the hero's mobile suit. Undoubtly the best gundam to date, soooo much firepower crammed into an already formidable unit.

However I favour more to Impulse's technology & versatility, mainly becoz of the various equipment that the pilot can switch depending on mission objectives.

Destiny tried to combine all the Impulse's technology into 1, personally I think they failed miserably because in the long run Impulse appeals more. Legend could have lived up to its name if were to be more fiercer looking and added a little more firepower to give SF a run for its money.

The rest of the MS are supportive like Zaku & Muramasa. These units are nuthing special, they are they to do what they needed to do.

Notable units worth mentioning, Saviour, pretty cool unit if the plane mode were to be much cooler. Plane mode, Muramasa's design looks better. Gorf Ignited, yes the short lived ZAFT's gold colored cyclops and lastly the shoulder mounted dual gatling guns from blue cyclops which didn't serve them true justice as these 2 units didn't see much combat.
