INDX looks second rate next to EY and its neighbours. It detracts from the view. The dozens of differently coloured balcony doors all over the facade make it look messy and unpolished.
With that said, the EY logo detracts from that tower's striking profile. The yellow sloped line of the logo is at odds with the direction of the sloped roof. It competes with the architecture for your attention, even though it's just a logo.
