Major difference to me between the loaded Laredo and the Limited was chrome and afraid am affected by the mantra of the '60s, "if it don't go, chrome it" (why my side rails are black).
OTOH the '14 base Laredo is currently (or not yet) available in only three colors, one radio (Uconnect® 5.0 AM/FM/BT), and the towing package is not an option. OTOH some things that required the "E" are now standard:
Remote Proximity Keyless Entry
Remote Keyless Entry
For me one requirement is the factory towing package which forces either a dealer install or the "E". (Why do you loose ECO mode if you get the towing package ? Since I only tow occasionally, that is not a good.)
BTW, with the LTD you also get the rear cargo cover (~$140)
For the 158th time since this pops up in every freaking thread now. ADDING THE TOWING PACKAGE DOES NOT REMOVE ECO MODE!
