Been a long time since I flew on AA but last minute trip to SFO and DL is all empty seats and looking bleak for F upfare.

AA is a reasonable upfare to F through our corporate portal. I seem to have 3 options all listed as having WiFi:

SFO - CLT - RDU listed as A321 (which from this thread sounds like LUS)
SFO - DFW - RDU also listed as A321
SFO - DFW - RDU listed as A321 (sharklets)

Oddly the two SFO - DFW flights leave 10 minutes apart but both connect to the same DFW - RDU flight (on a 738) that gets me in at midnight (vs. the CLT option which gets me back at 11pm).

Is the difference between the LUS and LAA A321s still that bad that I should dismiss the SFO - CLT flight as an option in favor of the SFO - DFW flight leaving 45 minutes later?

On paper, SFO - CLT seems better because it gets in earlier and since SFO - CLT is a 2200+ flight, would have whatever the top, non-JFK/LAX/SFO food service that AA currently offers vs. the two mid-cons which would be more scaled back.
