Ranked in these QuestionsQuestion Ranking
Pros
Pro Scalable, customized organization
Infinite row/columns and all the separate tabs to play with. Trips can be organized with as many attributes and calculations as you see fit.
Pro Good for budgeting
Since it is a spreadsheet, very easy to calculate budget, and any secondary calculations as well (e.g. cost/day, cost/location, etc.)
Pro Easy to share
Google Sheets are always accessible on the cloud, and easy to control permissions to share with relevant parties.
Pro Easy to export
Physically (printing) and otherwise (converting to excel, attaching to emails).
Pro Cross-platform
Can be accessed from any device via the browser, or Google's iOS and Android apps.
Pro Automatically creates itinerary
Once you link your e-mail to TripIt, it will automatically create your itinerary for you, instead of having to forward anything or manually enter the details.
Pro Access from anywhere
TripIt is available as a web app, with mobile apps for Windows Phone, Blackberry, Android and iOS.
Pro Easy to share trip plans
You can easily share your trip plans with friends and family so they'll know where you are.
Cons
Con Not optimized for travel
Unlike travel-specific websites, Sheets won't be able to tell if one link is a flight, and another is a hotel reservation, nor will it be able to know which cells correspond to what leg of the trip.
Con Zero foundation
While there are sample layouts (see Travel planner), it's likely that each person's trip planning needs will be unique enough that it's better to start from scratch. Of course, once you use Sheets for one trip, it'll be easier and faster to set it up for future trips.
Con Unreliable
App drops data, doesn't update promptly, throws all questionable emails into one "unfiled" bucket and leaves it to you to sort out.
Con Pro account is expensive
To make use of the features such as sharing itineraries, alerts and the seat tracker, you have to purchase the pro account at $49/year.
