I mostly agree with your order, but I think Alien and Resurrection should be theatrical cuts.

[SiL]

Alien TC is the only way to go.

Resurrection I feel you could take it or leave it, although that alternate intro is awful.

Yeah the "Director's Cuts" of Alien and Resurrection's the Theatrical Cuts as stated by both Directors.

Resurrection I feel you could take it or leave it, although that alternate intro is awful.

Agreed, The TC's intro was always a highlight for me.

Yeah but if someone's watching the entire franchise for their first time, the Prequels remain incomplete, and you want the first time seeing the creatures come to life on-screen to be their true first (and best) times on-screen.

I also arranged it so they dip in the middle in quality instead of leaving it on a sour note hence suburbia being back to back.

And with the Prequels being incomplete I elected to go with the thematic collective tissue between the last three listed.

Given a real conclusion and Skulls it might look different...

If Alien Awakening is canceled, it may be better to place the prequels after Resurrection. If Alien Awakening is released I think its better to watch it before the quadrology.

Yeah and currently it's in a state of non-existence as opposed to existence unfortunately.
