I have used FreshMag before, and I prefer it more than the other one
FreshMag is best for a tourism website..go for it..
I liked Impulse Theme. Great theme. I'd select Impulse.
The blog should be comfort for the visitors to read your blog posts.
I feel,discomfort with the Freshmag - home so i suggest you to go for Impulse theme as it is quite simple.
I am inclining towards arun's comment..i found freshmag cool initiall..but later on found it too much clumsy..i recommend you check out WP Omega at seojobsnow.com
I didnt like impulse much either...
