I DO NOT have the DID (door in door) unit in my new home, but in my old home. Note, the old unit never gave us issues but my post herein is about this model:
Shop the 31 cu. ft. Smart Standard-Depth MAX™ French Door Refrigerator with Four Types of Ice (LRYXS3106S). Discover LG's Reliable Technology.

We opted for no DID as we say little value in it over time.
This new unit, is larger than our previous DID model and this new one keeps temps incredibly well.

Of note, the compressor is a Smart Inverter.
Here's an explanation of this inverter:
Answer (1 of 4): They refer to different things. Smart inverter compressor is a marketing term, which means that the electric motor driving the compressor is fitted with an inverter, which is a variable speed drive. A linear compressor is a type of gas compressor. It is technically possible for a...

Specifically:
"A smart inverter compressor uses variable speed technology to adjust the cooling capacity according to the cooling demand, resulting in energy efficiency and precise temperature control. This allows the compressor to operate at different speeds, consuming less energy when the cooling demand is low and ramping up to full capacity when needed.
On the other hand, a linear compressor operates at a constant speed, leading to consistent cooling but potentially higher energy consumption. However, linear compressors are known for their durability and quiet operation.
In summary, the key distinction is that smart inverter compressors offer energy efficiency through variable speed operation, while linear compressors operate at a constant speed."
We bought this model because I wanted more size (interior for fridge and freeezer) and that it's handle-less. So it presents itself as a smooth flat face that doesn't grab your clothing when walking by. It has built in top-of-door handles and bottom-of-door handles (the fridge doors).
The freezer opens with a pinch press of your fingers at the top of the freezer slide drawer.
It also has sensing technology the the fridge illuminates when you approach it. This is a nice feature for evenings when you dim your house lights.
And the ice it makes, which is HUGE for us because we like ice, are those 4 versions; craft round balls, chips (small cubes), regular in-door cubes and crushed (in door has the crushed option).
I've been happy with both LG fridges for the past almost-five-years now.
Costco has this for a great deal right now PLUS you get a free 6 cu ft unit too for the garage (or friend or sell it or kids or whatever):
