The Izula definitely has a more ergonomic handle. It's blade also seems to be angled down a little, which helps with cutting leverage.
I've put an olivewood handle on the Becker, and upon heavy usage I found it VERY ergonomic. I'd actually love to see and Izula with a bit longer blade.
Also, I don't know why, but the Izula seems to hold the edge a little longer.
I'm going to make custom olivewood handle for the Izula also, and then compare them with pix and such.
Also, I really dig the bottle cap opener on the becker. I actually used it once to pop open a tomato jar. It is more useful than people credit it for.
