JR Tokyo Wide Pass or other pass

I will be going to Tokyo in March 2-7 I plan to visit the following:

Gundam Front
Disneyland
Mt Fuji
Shibuya crossing
Akihabara and other shopping places

I will be coming from Haneda airport

Is it worth to buy the Tokyo Wide Pass? Or other pass?

The Tokyo Wide Pass is really made for seeing good day trip places outside of Tokyo - and most of what you're doing is just staying within the city.
Going near Mt Fuji is the only travel of consequence you mention, and then you don't specify if you plan to see Hakone or the Fuji 5 Lakes area. For the 5 lakes you can get as far as Kawaguchiko, but otherwise you'd save money on one of the Odakyu passes.

Best case is you could barely break even on the Tokyo Wide Pass. Which is too bad since if you went to 3 of the furthest places you could on the pass - like Kusatsu, Karuizawa, Izu or Nikko, you could rack up about 20,000 yen in savings. And all are very worthwhile places.

For within Tokyo, look at getting a 2 or 3 day subway pass to save some money.

It won't get you all the way to Disneyland, but the fare is not high to there anyways (see their website).

It would be cheaper to get a return bus from Shinjuku for Mt Fuji and use an IC card for your inside Tokyo travels.
