Upgrading Gear

[eagle3190]

Hi guys my name is Dario, from Italy but living in Sydney and i'm about to upgrade to " Enthusiast
" my gear.
So I've already decided for the canon 70D but i'm not sure about what lens.
I could get the bundle with the 18-200 but i think with this kind of camera i need to invest in something more for the lens.
So my doubt is between the Sigma 24-70mm f2.8 and the Canon EF 24-105mm f/4L IS USM.
The main purpose would be travel photography as i'm about to go in Thailand and after India.
So what kind of lens would better? I have to say that I kind of like the macro so the sigma would better having a focus distance of 0.30 cm but with the canon i have more zoom range which is better i guess for travel. Which lens should i buy? Or even other lens with a budget around 600$. Thank you, if you will find the time to reply me!

P.S. This is what i think i gonna buy with a budget of 3000$. Let me know what you think!
