Here is an opinion I found on Reddit. I wonder if someone like @DUTCH can help or point me to more info.

Here are some corrections (NA Market Only): 1. M113 Came in 2002 - 2008 in the G500 - Very reliable 2. AMG M113 (no supercharger) came in only 2003 - 2004 in the G55 - Very reliable, but very uncomfortable due to the stiffer AMG suspension
3. AMG M113K (with Supercharger) came in 2005 - 2011 G55 (identified by the 'Kompressor' badge) and from 2005 - 2009 it was pretty much the same car, but 2010 - 2011 got some updates - Very reliable as well and there isn't much of a difference in maintaince costs compared with M113 other than additional pulleys needing replacing, and a premium price on AMG specific parts. These years also reverted back to the more comfortable G500 suspension
4. M273 came in 2009 - 2015 G550 (new engine + new name), and these aren't as reliable as the M113. They aren't bad, but they do have timing chain issues, but they're definitely not a BMW engine. I'd personally go for the G55 of the same year
5. M157 AMG came in the 2013 - 2018 G63 - Not very reliable... early ones are known to burn a lot of oil, and same can have compression issues which totals the engine. These also are the first g wagons with twin turbos, and there have been some reports of the turbo's failing. Overall would not recommend..
6. M176 came in the 2016 - 2018 G550's and G550 4x4. not too unreliable.. but not as reliable as the M273. 7. M120 AMG V12 came in the 2016 - 2018 G65. This is a very reliable engine and there are no known issues with these engines (coil pack issues been resolved from the earlier versions), however, expect high maintenance costs since there isn't a lot of room to work on these cars, and high parts prices on AMG V12 components. Overall, my favorite is the 2010 - 2011 G55 AMG. Great interior quality, better tech than the early ones, terrific reliability, and great performance (some say its just as fast if not faster than a G63).
