The advantages of spending the extra £££ on something like the Morimoto 7.0 are: a proven durable reflector coating, proven reliable solenoid mechanisms, a confirmed very-wide beam pattern and a higher concentration of light at the cut-off (rather than on the ground in front of the car where the glare will contract your pupils and reduce your ability to take see into the distance).
The thing is, it's hard to know what you have so you can't be sure what benefits you would get from upgrading.
Besides...you are soooooo much better with cheap projectors than you are with a halogen setup that it's all a bit of a moot point. Enjoy!!!
