DeWalt DWS780 vs DWS779 vs DWS709
The DWS780 and DWS779 are the same except for the fact that DWS780 has the XPS light and model DWS779 does NOT have a work light. According to DeWalt customer service, the DWS779 does NOT support the XPS light.
As compared to DWS709, the DWS779 and DWS780 have a larger cutting capacity, taller cutting capacity of 6.75″ versus 4.5″ on the DWS709, horizontal cutting capacity of 14″ versus 9.5″ on the DWS709, DWS779 and DWS780 cut up to 2inx16in dimensional lumber at 90 degree and 2inx12in at 45 degree whereas the DWS709 cuts up to 2inx14in dimensional lumber at 90 degree and 2inx10in at 45 degree.
The DWS779 and DWS780 have adjustable depth stop whereas the DWS709 does not feature.
The DWS779 and DWS780 have preset bevel stops whereas the DWS709 does not.
The DWS779 and DWS780 have a cam lock whereas the DWS709 has a twist knob.
The DWS779 and DWS780 come with a 60-tooth blade whereas DWS709 include a DW3123
32-tooth blade.
Just like the DWS779, the DWS709 does NOT have work light.


DeWalt DWS780 vs DW716XPS (DWS779 vs DW716)
The major difference is the cutting capacity and sliding feature. The DWS780 is larger than the DW716XPS, it is heavier, has a larger cutting capacity than the DW716, and the DWS780 is a sliding compound miter saw whereas the DW716XPS does not slide.
The difference between DWS779 and DW716 is similar to the above, because the DWS779 is the DWS780 without the work light system, the DW716 is the DW716XPS without the light.

DeWalt DW716 vs DW715
The difference between them is that the DW716 is double bevel whereas the DW715 is single bevel.
A single bevel miter saw will tilt the blade only to one side, left or right.
A double bevel miter saw is able to tilt the blade to both direction, left and right.
To make it short, a double bevel saw makes it faster and easier for making bevel cuts, it allows you to make certain bevel cuts without having to flip over your work piece. However, with the single bevel saw, you still can get your work done, but maybe a little more time and effort.

DeWalt DW716 vs DW716XPS
The DW716XPS has the XPS light whereas the DW716 does not include. The DW716 Type 20 is NOT compatible with the DW7085 addon XPS system.

DeWalt DHS716 vs DHS790
Both of them can be corded or powered by batteries. The major difference between them is that the DHS716 is a fixed miter whereas the DHS790 is a slider. The DHS716 is smaller, lighter, allowing smaller cuts. While the DHS790 is larger, heavier, it has lager cutting capacity with the slide, and it is also more expensive.

DeWalt DHS716AT2 vs DHS716AB vs DHS716T2
The difference between them is what they includes.
The DHS716AT2 includes DHS716 12 in. (305 mm.) Compound Miter Saw, Blade, Blade Change Wrench, Dust Bag, Two 60V Lithium Ion Batteries, Dual Port Fast Charger, 120V AC adapter.
The DHS716AB includes DHS716 12 in. (305 mm.) Compound Miter Saw, Blade, Blade Change Wrench, Dust Bag, 120V AC adapter.
The DHS716T2 includes DHS716 12 in. (305 mm.) Compound Miter Saw, Blade, Blade Change Wrench, Dust Bag, Two 60V Lithium Ion Batteries, Dual Port Fast Charger.

DeWalt DHS790AT2 vs DHS790AB vs DHS790T2
The saw unit is the same, the only difference between them is the included things.
The DHS790AT2 comes with DHS790 12 in. (305 mm.) Compound Miter Saw, Blade, Blade Change Wrench, Dust Bag, Two 60V Lithium Ion Batteries, Dual Port Fast Charger, 120V AC adapter.
The DHS790AB comes with DHS790 12 in. (305 mm.) Compound Miter Saw, Blade, Blade Change Wrench, Dust Bag, 120V AC adapter.
