Which porygon is better?

Question

So I have a porygon with analytic and one with trace
And I am wondering which is better,
The one with trace has
Trick room
Tri attack
Pcyshock
Recover
And has a sassy nature

The one with analytic has
Toxic
Pcyshock
Tri attack
Recover
And had a bold nature

So which is better?
Better as in competitive playing, cuz y'know how people say better and you don't know what they mean.

Answer 1

Sassy w/ Trace for sure.
Sassy is great for Trick Room, which screws over many an unprepared team. Just take out Psyshock for Ice Beam and you'll be golden. Here's what the set should look like:

Porygon2 @ Eviolite
Ability: Trace
Sassy Nature
252 HP / 160 Def / 20 SpA / 76 SpD
-Trick Room
-Ice Beam
-Tri Attack
-Recover

That's all! Hope I helped!
