Dinan S2 e53 4.8is or 08 e70

[4.8isguy]

I'm having trouble deciding guys. I currently have a 04 4.8is with 108k miles. Come's pretty much fully loaded from the factory. I have an opportunity to get into an 06 with 60k miles for a small price with all the important maintenence done on it. I have all the dinan goodies minus the exhaust laying around at home to turn this into a full Dinan S2. All I would do down the road is some Brembos and maybe an NBT retrofit somewhere down the road. I am a big fan of the e53 platform from the handling, the sound, to the overall styline but the e70 has the updated electronics and is an overall updated car and a new platform for me to play around with. I've had two e53's in the past 4 years(3.0 then 4.8is). I'm thinking the e53 is probably a much funner car to own but looking for someones opinion thats had both or driven both.
