Ranked in these QuestionsQuestion Ranking
Pro Best support for Gmail features
Since both the Gmail Android app and Gmail itself is made by Google, the app supports all features Gmail offers (like labeling/starring) and gets new features implemented early - usually as soon as they are announced.
Pro Incredibly fast, advanced & predictive search
Gmail brings much of the functionality and power of Google's search engine to the app's search. You can use operators such as label:, is:, OR, has: among others, define date ranges, limit search to specific groups and so on. And, you can do it all amazingly fast. The search will also try to predict what you're trying to search for before you've even finished your query and offer up those results.
Pro Comes bundled with Android for free
Not only is the application free, it comes bundled with the Android OS by default so you don't even have to bother downloading it.
Pro Google Drive integration
The app allows inserting files from Drive straight to email or uploading attachments to Drive before sending them out. It will also notify if the person you're sending the file can open the file or if you should change the sharing settings for that file beforehand. Finally, you can choose which one of your Google accounts you want visible in the app.
Pro Safely automatically displays images
The app does not require a confirmation to show images as Google now hosts the images on their own servers making it safe. You can still disable the automatic displaying of images in the settings if you wish.
Pro Google Calendar integration
Pro Tabs to automatically organize your e-mail

Con Sorting mail by Unread is unintuitive
Nearly every other mail app has a clear way to sort mail by Unread. In Gmail app you can do that only by typing “label:unread” in the search field.
Con Very limited HTML composing
Composing of HTML formatted mails is very limited. No inline images and only some basic text formatting options
Con No intrinsic p2p encryption option
Con Too heavy
It should be lightweight.
Con Limited notification buttons
Con Costs US$79.95 for just the Personal version
Con Stores in a proprietary format
It stores the whole database in a proprietary file package, that you cannot easily access from another app or from the Finder. Considering you might be classifying a huge quantity of files there, it is quite problematic if you want to interact with this data from other applications.
Con Non free/libre (proprietary)
Con Only runs on Macs & Web
DEVONthink has not seen any major update in the last 5 years at least. Its interface still ressembles PowerPC era Mac OS X and it has not kept up with the evolution of other apps and services that could interact well with it. Most of its functionalities (e.g., OCR engine) are not at the level of current technology.
Con Very limited automation
While the marketing claims are about an intelligent document manager, it actually does not offer many automation features, such as automatic classification, tagging and renaming of the files. It's much more like an extended file explorer.
