I've already answered this in other threads, but for ease....
Tenergy 05:
• Easier to generate spin on slower shots (good if you have a slower arm speed or find yourself out of position a lot.
• Softer sponge, but it's not an issue after some practice.
• Bouncier and more spin responsive - Makes it harder to keep the ball short on serve receives or touch shots
• Higher arc - More of a "traditional" loop arc (like a nice big rainbow).
Dignice 05:
• Harder sponge - Again, after playing for a while, I don't think this is an issue
• Lower arc - Despite the increased spin on a similar shot, the ball will fly lower to the net in more of a straight line. This is very deceptive and people will misjudge the sheer amount of spin on the ball.
• Top end spin is greater.
• Less spin responsive, which makes control and touch much better.
