I don't know how they compare, but you need to look at the torque and HP curves of both. I know the little turbo engines from Ford produce much better torque at low RPM compared to the V8, even though the top numbers might be lower.
This is year 3 for it...I have a 2015 Silverado with the 5.3L V-8. I love that motor and would not consider a 4 cyl turbo that has the published specs- especially in year #1.
YMMV

I thought about it, but the emissions equipment scares me.Have you considered the little inline 3.0 six cylinder, I drove one a few weeks ago.
It's an impressive little motor with great torque.
It is auto 4x4, not AWD. Only one wheel up front grabs, the rear has the G80 Locker which only locks when needed. There are clutch packs in the transfer case that lock when a when needed. And 4Lo is optional, only standard on certain models, such as the Trailboss.It's got 2 high, AUTO, 4 high, and 4 low. AUTO is part-time AWD, where it sends all the power to the real wheels until it detects wheel slippage through sensors, then it sends power to the appropriate wheels as needed.
4x4 splits 50-50 between front and back all the time.

I believe the 2.7 hair dryer will replace the 4.3 V6,no big loss there ,owned a couple in full size trucks.They were o.k.but not much better mpg than a V8.
I have seen 23mpg on the high-way with the 5.3 V8 with my last four full size trucks.
The 2.7 would make a nice motor for the Colorado also.
Just bought a 2020 Jeep Rubicon 2 door with a 2.0L gas turbo. We were all set to buy one with the 3.6L V-6. Once we saw the specs on the 2L, we were sold.
We drove both and found the 2L much smoother, more linear and much quieter on acceleration. It actually has more torque than the 3.6L.
I am a big fan of Diesel engines and fully understand what turbocharging does. Its an amazing way to pull much more power off a smaller displacement engine.
