Hi @ofolis, I'm back with some comments as I promised.
I took a screenshot of the same code in all three of the fonts and pasted it together:

I absolutely love how you made the lines in the ==, === etc ligatures spaced exactly like the two lines in the original = sign. One thing that doesn't quite add up is the slash in the != and !== signs being drawn a little bit too high.
Compound assignment operators aren't really ligatures except for /=, which seems fine to me.
I must admit I'm not a fan of the ligatures made up from < and >. I find the ones in Ligaturized Consolas look better overall. Though I love when the lower stroke in >= and <= is drawn horizontally. What doesn't look very nice are the < and > parts themselves.
Logic operators look fine to me, as they're made from standard Consolas glyphs.
Also, for some reason, the double quote character looks a tiny bit different in Consolig compared to the other samples.
I probably missed many other ligatures, but these are the first ones that I thought was worth inspecting.
