Accor is generally poor in Bali for some reason.

If you're staying at the resort most of the time I would avoid. Meal time for example is a horrible shopping mall experience. If you're super keen a pool access room would be great.

The Grand Hyatt is older but bigger and far more serene and slow paced, especially in the club. The Westin is a also nicer middle ground.

If you're not wanting to stay in the resort I would instead head to Sanur and go to the Fairmont or Hyatt Regency.
