ignition ststems

I'm currently re building my motor on my 2008 crf450. i had the head ported and polished. i am using a JE pro series piston, along with a complete yoshi exhaust. i was looking at ignition systems and two were recommended. there is the vortex ignition and the Dynatek. i am wondering if any one else has one of the two and could let me know what they think. after all is done it should put about 53 HP to the real wheel compared to around 43 of what it comes stock.
