Cascade is an all-purpose, responsive (mobile friendly) theme with 12 optional layouts, per post layouts, multiple drop down menus, 12 widget areas, support for all 10 post formats, and mobile compatible menus.
Gommero is simple, elegant, and easily customizable.
I use cascade theme for my personal blog. Actually it is awesome WordPress theme. 🙂
Gommero is also one of the best available WordPress theme, loved it 🙂
Now a days i prefer something more like Gommero. I like Cascade but the only downside to it was it would not adjust spacing for widgets so, some would need to be re coded, or body content box needed to be shortened. Glad their both available, more variety makes content more unique.
I like very much the Cascade theme, I use it for one of my blogs. being responsive is quite important nowadays, with so much mobile traffic
