Not questioning your integrity at all. Just curious how you arrive at such negative opinions about a subject that is generally very well regarded by consumers, piers, and professionals.
Proclaiming the 2.7L EB "is a turd", and that the GM/Ford 10AT "leaves a lot to be desired" would tend to have one believe you've had a bad experience with both. My experience has been extremely positive, so it's a bit perplexing to me what led you down that negative road. That's all. Trying to understand how you formed those opinions. If I didn't want to hear your opinions, I wouldn't be asking!
So far, we've determined that, because the 3.5EB is more powerful, and your friend wanted the most powerful engine, that alone apparently makes the 2.7EB a "turd" as you say. Interesting conclusion, but sure, if it works for you.
Then you proclaim the GM/Ford 10AT "leaves a lot to be desired", but no explanation as to what it is you desire more of. Perhaps you could sum this up, then we can move on.
I just hate unfinished thoughts.
