Just too much information, each manufacturer is obviously "the best".

So from what I've been able to weed through via the boards is an SCT Tuner has the most options and ability to DL and install custom tunes.
There is also a Livewire version which is bluetooth capable and has a "real-time" display of engine parameters. That's a plus instead of relying on the lie-o-meters in the cluster.

What's your experience?
