I don't know why, but most of the must-see 'emblematic' monuments in Buenos Aires (a city with amazing architecture and breathtaking views) like El Puente de la Mujer, are pretty disappointing white bland structures. The Obelisco is not the exception. Not only it's located in a quite inconvenient area for tourists to be (it's busy as hell, which also means that it's quite dangerous), but it doesn't really offer that much of a view. In my opinion, anything else about what surrounds the Obelisco is worth the trip.
If you're in Buenos Aires on holiday, I'd recommend dropping by only on your way to visit the Teatro Colón, the Supreme Court or the Avenida 9 de Julio itself (but be careful with some of the drunks in the poorly-lit squares).
I've said this before, but do take care of your belongings in the area. Not only because there's plenty of pickpockets there during rush hour, but also because there are some spur-of-the-moment celebrations, gatherings, demonstrations, and you never know what you might get.
