Careful; those are fighting words. Be prepared for the onslaught of people who will lay claim that ALL LUS A321s are outdated, old, uncomfortable, etc.

In all seriousness, other than an overabundance of the use of blue (with little contrasting color), I found the LUS A321s to be just fine. Sure the lack of IFE/power ports can be a drag but with a charged iPad/working wifi there is little to no difference. The claims of worn-out/dirty planes is over exaggerated greatly as the majority of the 321s were delivered after the US/HP merger. The only complaint I ever had was the goofy kidney-shaped tray table they have in F.
