Here is my top 5, 5 being lowest 1 being the best!
5) 2002 Jango Fett. One of my favourite characters in lego form and has a really iconic helmet design in my opinion.
4) Rebel Scout trooper. This one is a bit of an odd choice but I just really love the simple design as it has enough detail for what it is, a trooper. Also I'm absolutely in love with the helmet as well. All in all a great figure.
3) 2002 Clone Trooper! I just really love the episode 2 clone trooper's armour design and I think the original 2002 design is the best version.
2) Old Shadow Trooper. For a simple recolour of a Stormtrooper it's really quite amazing, the colours are striking and make the figure really stand out (Not a good thing considering their role) while not being an eye sore to commanding all your attention. Points for being army build-able.
1) Finally, my number 1 Star wars figure is...................The Battle Droid! Really just a great solid figure, never seen it bre- I'm joking of course :P
1, for real this time) The original Grand Moff Tarkin. More of a nostalgic choice than anything else, I remember getting the original star destroyer when it was released and absolutely loved the set (Currently trying to obtain it again). While I loved the Imperial Royal guard, Tarkin just sort of became my favourite from the set. He has good simple but detailed design and stands out from the other officers with a slightly different suit and higher rank insignia.
