I think the MKZ Hybrid at 41/36 MPG is better than any comparable vehicle in the market. It blows away any comparable that it's not funny (for those competitors).
I think that the MKS EcoBoost at 20 MPG overall that returns 355 HP is better than its Cadillac comparable -- all configurations of the CTS Sedan (I'm going to leave aside the more exotic variants, like the CTS Wagon, for now). (The CTS V6 returns 21 MPG at 304 HP; the V8 returns 556 HP -- which, in my opinion, no sane human requires -- and does it at 15 MPG and requires premium (the V6 does not).)
Sure, both of those models in their "basic" configurations are not terribly exciting entries, but a buyer does not have to settle for the "basic" configuration. As properly configured, they're very strong entries.
Lincoln's weaker entries right now are the MKX and the Navigator, but both are due for overhauls, with the next MKX arriving very soon now. The Navigator, in my opinion, is what's giving Lincoln a bad name right now as it looks awful compared to the other luxury car makers' offerings. No other Lincoln vehicle really has that kind of an effect.
