Haunting guise versus Hextech Revolver. Hextech Revolver the most populair item on vladimir early will grant you:
 * 40 ability power
 * 56 health
 * 12% spell vamp

Haunting guise for a mere 285 gold more you get:
 * 30 ability power
 * 235 health
 * 20 magic penetration

In total when comparing haunting guise to hextech revolver:
 * you spend 285 more gold
 * you loose 12% spell vamp
 * you do 6 less damage on Q
 * your W costs 47 health more but do 8.8 (35) more damage
 * you loose 4.5 damage on E
 * you loose 7 damage on R
 * HOWEVER, you gain 20 magic penetration (depending on their rune-set and masteries) this will double your base damage output.

Most mages out there have only 30 magic resistance and no scaling per level... So if you couple it with your next buy, which will probably be sorcerers shoes, you can actually decrease their magic resistance.

This makes your spells with hextech revolver deal your base and bonus damage on 91%. While your spells with haunting guise will deal your base and bonus damage on 122,5%

Then a level 3 Q will deal 165,6 damage with hextech and 218,05 with haunting guise. While giving back (165.6*0.12=19,872 from spell vamp)45 health and 42.5 health respectively A level 3 W will deal 42.75 damage with hextech and 67.56 with guise and give back 10.47 health and 8.44 health respectively A fully stacked level 3 E will deal 214 damage with hextech and 280 damage with haunting guise. A level 1 R will deal 160,2 with hextech and 209.5 with guise.

NOTE that these numbers will get closer to each other the more MR the opponent has. So later in the game Hextech revolver will do better.

TL;DR

Paired with Sorc's boots, Haunting Guise will deal 31.5% more damage early game compared to a Hextech Revolver at the cost of minimal sustain loss(2 on Q, 8 on W (2 per tick), 25 on E and 7 on R).
