Help me choose my special sweeper, /vp/.

Porygon-Z Pros:

Z-Conversion is nuts. +1 to every stat and a type change.
Boltbeam
Recover OR Shadow Ball

Porygon-Z Cons:

Needs a turn to set up
Can be OHKO'd somewhat easily with those defenses.


Alakazam Pros:

It's fucking Alakazam, hits like a truck.
Faster than a truck.
Can't be OHKO'd since it'll hold a Focus Sash.

Cons:

It's Alakazam. It's like a piece of wet paper.
It has to hold a Focus Sash over say a Life Orb.
Seriously fuck looking for a hidden ability Abra.
