If given the choice I prefer a non-powered trunk opening. Opening and closing a trunk provides no hardship for me, and doing it myself is much faster than waiting for a mechanism.

Being able to pop your trunk (and have it open) on your approach to the car is actually quite convenient. I didn't think much of it until I had the option. I wouldn't call it a deal-breaker though.
Are you in a race to get going? I can't see you being in your seat, buckled and engine started before the mechanism closing? Not being snarky, it's just not that compelling a reason - to me.
