My comparisions:
Graphics:
Pokemon- 8/10
DragonBall- 7/10
DragonBall's graphics are good but are not 3-D even for a second. emerald is 3-D for 20 seconds

Sound:
Pokemon- 5/10
DragonBall- 9/10
Pokemon background music is cool but default volume is low. Sound of DragonBall is great. Volume is high too.

Gameplay:
Pokemon- 10/10
DragonBall- 8/10
DragonBall gets boring at times. Pokemon has fantastic gameplay throughout.

Difficulty:
Pokemon- 7/10
DragonBall- 10/10
Buu's Fury may be the simplest DBZ game ever but it still beats Pokemon by a long mile.

Game Legnth:
Pokemon- 8/10
DragonBall- 7.5/10
Pokemon games have no comparision when it comes to game legnth.

Story:
Pokemon- 8.5/10
DragonBall- 8.5/10
The story of both the games is brilliant.

Repeat Value:

Pokemon- 8/10
DragonBall- 9/10
DragonBall is great when it comes to exploration.

Mini Games:
Pokemon- 5/10
DragonBall- 1/10
Pokemon may not have good MiniGames but they are better than DragonBall's.

Overall:
Pokemon- 7/10
DragonBall- 6/10
Pokemon is statistically better, but i say, go for Dragon Ball Z- Buu's Fury.
