Switching to Lumia 730 from 720, what would I miss?

[Ebuka Allison]

Why oh why Fahmi? The 720 is such a great phone. I am due for an update at the end of this month and seriously debating whether to go for the 830, 640 or just keep my trusted 720. I really like glance, wireless charging and dedicated camera button. Decisions, decisions. Any useful suggestions anyone?
P.S. I have relatively small hands so no XL for me.

The 830 has all those.

I actually fall in love with my 720, but it's time to change, I like how does the 730 look, especially in green!
Whenever I think about this, I feel that "WTF I'm thinking about"
