Pros
Pro Open source and free
Pro Live preview
You can live preview fonts in multiple ways - you can view a single word, a sentence or a paragraph with text and font-size of your choice. There's also a poster view that tries putting more fonts on screen at a time by showing only their name without the option of entering your own text, and is the only view option that allows inverting background and text colors.
Pro Easy to filter through fonts
Within categories such as serif, sans serif, monospace, etc, you can adjust desired thickness, slant, width and script to filter the collection of fonts. Additionally, you can also set how you wish to order the fonts (by popularity, alphabet, date added, etc).
Pro Sizable collection of fonts
There are more than 600 fonts to choose from.
Pro In-depth font comparison
Once you've added at least two fonts to your collection you can compare them closely by overlapping them in the compare view. Simply click the review tab at the bottom and navigate to compare tab at the top.
Pro Great for web designers
This repository was designed specifically for web designers. As such it shows the impact of the font choice on page load time, allows selecting only the font styles and sets you need to reduce overhead, and gives multiple methods of integrating the fonts into your website.
Pro Integrates with Typecast
With fonts you wish to use selected, go to review tab at the bottom and click 'Try in Typecast' at the top. Typecast has an easy to use WYSIWYG editor that allows quickly prototyping and testing out chosen fonts.

Pro Clean and helpful UI
The panels in Gravit adjust to contain the information needed based on the type of element selected, preventing the clutter that Photoshop often experiences.
Pro Easy to design multiple pages
The ability to assign layers to specific pages, and view single or multiple pages at once makes it easy to design an entire website without getting lost in thousands of layers. Easy to view multiple pages at one time.

With Gravit you can re-use the same design for buttons, inputs, etc, in multiple places, with changes synced every where the element is used. It's also possible to set text to a shared style to sync text changes throughout the app.

Cons
Con Stale font versions
Con Mainly focused on latin family
Con Paid version
Expensive paid version that has many features you can find in free or cheaper applications.
Con This does not appear to be a Web-design tool
Gravit appears to be a vector-art tool, and nothing more. Their homepage doesn't even mention Web design as far as I can see.
Con Changing rapidly
The fast rate of growth/change for Gravit can be a pro in that in means plenty of new features.
However, it also makes the product fairly unpredictable.
For example: In the past year, Gravit was open sourced, then closed sourced again.
