  In this proceedings we compare phenomenological predictions for differential
distributions in top-quark pair production at the LHC. In particular we
consider NNLO QCD fixed-order predictions and parton-level predictions based on
NLO QCD multi-jet merging following the MEPS@NLO scheme. In both predictions
NLO electroweak (EW) corrections are incorporated in different approximations.
We focus on several transverse-momentum distributions and on the top-quark
invariant mass distribution, both highly relevant for the ongoing physics
program at the LHC. We discuss comparisons between the different considered
approximations and their advantages and disadvantages for different
distributions.
