My Uninformed opinion is that pick the one you feel will best support what you want to run. 2014 is a known quantity and if you plan on running modules, it's more than adequate. Level Up is good if you want a crunchy Pathfinder-y feel to 5e and don't mind doing a lot of prep work to convert and replace modules or make your own. TotV is basically an alt version of 2024: close enough that everything works, different enough that it doesn't work perfectly. A good compromise between 14 and LU.
