Which of these strategies is better in the long term? Which is riskier?

Still trying to figure out what CANBUS does in the context of an N55 eginine and tuning applications.

Thanks
I have had 2 JB4's (e90 and f30) and now use only MHD. I chose MHD over BM3 mainly because I can use it via my android device as opposed to a laptop. There is no doubt that the flash tunes provide a more natural power boost and I would deem as superior at this point. Go with a flash is my advice.
