If the Grand Prix was in production today what engine would it have? I'm assuming it would be the same engine found in the Impala, correct?
How does that engine compare to the reliability of the 3800?

It doesn't.
It's like comparing the Wright Brother's airplane to an F16.

The new 3.6 V6 is very powerful compared to the 3800 but it's not without lots of little issues.

So more powerful, but not as dependable. Personally, I prefer dependability and reliability. I'm not going to track or racing on streets.
What issues does the new engine have?
What engine does GM currently offer that is as dependable as the 3800?

The early 3.6's all suffer from oil leaks, timing chain failures, intake valve coking problems because of the direct injection system. The last few years have several revisions and problem fixes so I haven't seen heard as much yet with like 2015+ models.
Any new car with a warranty I wouldn't be that concerned with.
GM's V8 line up is proven dependable.

My dad has a 2006 grand prix 3.8 liter, and the impala with the 3.6 liter. He says the 3.6 (with over 300hp) feels gutless compared to the 200hp by the Pontiac 3.8. The transmission is soft feeling when shifting and it just doesn't seem to take off like the pontiac.

Torque.
Torque is the deal.

225 in the 3.8 vs 264 in the 3.6.

Gearing and where the torque comes in in a major factor.
The 4 speeds had very long gears and the torque came in full way down between 3500-3800 where as the 3.6 makes all it torque above like 5,300rpm.

I've had to borrow a car before, and honestly I preferred his base Grand Prix over his impala ltz. Hell I'll keep my Grand prix before I'd take the impala. All the bells and whistles are nice, but no thanks.

Honesty I don't think any New V6 engine these days would be comparable to the 3.8, on reliability
This is also coming from a person who can't stand ANY newer cars 2010+ RIP Pontiac
