Tyranitar is NOT better.
Let us examine the power of both decks.
TTar: Main attacker...Weavile: Charger...HP: 140HP...Damage: 30 spread...
Giratina: Main attacker...Togekiss: Charger...HP 150 (w/ SP temple, FOR A BASIC!)...Damage: 30 spread + lost zone
The way I see it, T-Tar takes T4 to charge up. Giratina can be T2 if you get at least 2 energy on togekiss's serene grace...as T1 you attach and T2. Also, I can see an absol stall that works to make your opponent's setup slower and helps with giratina's body.
Giratina also can send pokemon to the lost zone. No TSD, NM, or anything can get you that in DP-PT.
Giratina takes 4 energy. T-Tar takes 5.
Giratina can start as the starter. T-Tar needs weavile.
Togekiss doesn't waste an attack like weavile, can sit the bench, and get up to 10 energy...(I would play 16 ENRG in Giratina)
Giratina is weak against {D} and Drapion/T-Tar is dark. T-Tar is {F}...Gliscor, Machamp, Pardos, Kabutrouge, Lucario rogue.
Giratina takes less time to charge, lost zone, more HP, poke body, let loose power, etc.
