LA has a great lineup while DL hasn't been spectacular (was that polite enough) for some time. LA has never restored a PDB - just water at the seat, and doesn't have a real pre-meal beverage service - if you're lucky, they'll come around passing champagne after takeoff. DL has the typical int'l PDB (bubbles, juice, water) and post-departure beverage and nuts service. LA gives you a mattress pad and blanket. Amenity kits are marginal on both. Last DL flights to/from South America - September. Last LA flights, June.

Even though the comments would leave you thinking its a wash, similar fare, similar time, I'd take LA. But lower fare, I'd take the lower fare (if it were more than $100 or $200 difference and points accrual weren't an issue).
