Did the stats at 600 AP: a lich bane proccs adds 500 damage, using DFG with full combo adds 927 damage. The more AP you have, the more the advantage goes the Lich bane but you shouldn't reach a point in the game where Lich bane passes DFG (2848 AP).

So we have Lich bane:

Pro:

Sustained added damage (not one use)

Independent from availability/use of high cooldowns skills (W, E and R)

Added movement speed

A bit more mana (more spamming)

Con:

Less full burst compared with DFG

Need to get close to activate procc (low range of veigar: 525).

DFG:

Pro:

A bit more AP than lich bane

15% cooldown reduction

More full burst than Lich bane

No need to get close

Scale from enemy health

Also boost your allies magic damage

Con:

One use per 60 second: dangerous if you missed your shot, can't be used to harass or on different targets. It's all or nothing.

Reduced power if your skill are in cooldown (the 20% damage boost mostly wasted if R and W not ready)

Built from an expensive item (1600 gold not easy to gather at once)

On conclusion, getting both would be the best. Most of the times, you'll need to consider the state of the game to see what you need: do you need more burst ? Do you often have times when you could have finished an opponent if you add an additional skill ? Do you have an ally dealing magic damage ? Are you too slow ?
