This is probably a stupid question as there's going to be a myriad of answers, but I had been thinking about this. Not necessarily for myself, but to satisfy my curiosity.

If money wasn't a big deal breaker in the equation which engine (out of the box) would be the one to get? I'm not talking about buying an engine and sending it in to somewhere for work to be done. I mean as it comes out of the box. There is much talk about best bang for the buck etc. What if someone was willing to spend more?

I did not want to hijack the other engine thread with my question even though it's along the same lines.
