In the end, i find I have and use both - they're so cheap, why not? I like the Navionics for 'dreaming', for quick looking at an area, and for quickly measuring a distance I'm curious about. It boots so much more quiickly it's more efficient for those kinds of questions. I use it sort of like i might a paper chart. But for true route planning and navigation, iNavX has it hands down. However, if the Navionics app could export a route, I'd probably create it in that, then use it in iNavX. Also, if your route goes between chart regions, the Navioinics app is not really an option.

Added - the Navionics app also has a decent directory of marine services (marinas, chandleries, yards etc.) and restaurants, and a rather nice tides and currents all accessible within the app. I really wouldn't want iNavX cluttered with all that, but it's nice to have it handy in another app that just happens to include a chart!
