The grid layout with the predefined CSS elements and JavaScript components make it easier to have consistency across different browser versions and even different devices.
Question Ranking
Pros
Pro Consistency across browsers
The grid layout with the predefined CSS elements and JavaScript components make it easier to have consistency across different browser versions and even different devices.
Pro Responsive design philosophy
Bootstrap is developed to be instantly compatible with all sizes of screens, so you don't have to worry about which device the user is accessing your site from. Yet if you prefer, you can disable responsiveness of Bootstrap.
Pro Well documented
Documentation is thorough, well organized and full of live examples and templates ready for use. Every component and every part of the framework is explained and covered in depth.
Pro Custom builds
If you don't want to download the full Bootstrap framework. Custom builds of Bootstrap can be created, including only the desired CSS, CSS components, and JavaScript components. This can be done directly from the Bootstrap website by simply choosing what components to download.
Pro Designed to get a site running quickly
Bootstrap is designed to get a site up and running quickly. Each of it's components is pre-configured to help with getting a site up and running quickly.
Pro Great community
Bootstrap is very popular and has a large community. As a result of this it is much easier to find help with anything you might need. This also gives you a treasure trove of prebuilt components to use and add to your site.

To help you avoid the "Bootstrap look", there are many resources that provide a great selection of themes and templates for Bootstrap.
Pro One of the most popular ones
Ranked on GitHub as the most starred CSS repository.
Pro Flexbox-based
The whole framework is built on flexbox and works really well on most platforms.
Pro Active developer
The developer is actively maintaining the project and responding to any issues and questions.
Pro Minimal
The framework is really tiny, under 7KB gzipped.
This is what makes mini.css stand out, because it looks like a pretty powerful library and it still is under 10KB.
Pro Responsive
It works great on all devices, mobile websites are really easy to develop and view.
Pro Style-agnostic
Few flavours so far, but there is a lot of space for customization.
Pro Great documentation
From basic syntax, templates, examples, customization to-dos and don'ts. The documentation is pretty great.
Pro Supports CSS custom properties (var)
No other framework supports CSS variables right now (as of November 2017). The latest alpha of mini.css supports this feature, making customization even easier.
Pro Accessible
ARIA rules are a priority and it works very well for all users.
Works really well with screenreaders.
Cons
Con Large file size out of the box
Bootstrap has an out-of-the box filesize of ~276K, which is pretty large considering it's just CSS. Most of those styles aren't even used in 90% of web pages built with Bootstrap. By only including the required styles it can be trimmed by 70%-75%.
Con Too many classes
Bootstrap's over-reliance on HTML classes for styling can get very messy very quickly. There's also an overabundance of DOM elements which have a lot of classes and are more often than not nested inside DOM elements with even more classes. This gets problematic down the line because the maintainability of the project gets harder when the project starts to get large.
Con Websites can start to look the same
If the initial Bootstrap colors and styles are not changed or edited, different websites start looking the same even if they have nothing to do with each other and they are made by different developers.
Con Hard to customise
It's quite hard to customise Bootstrap using pre-processors like SASS and LESS, the only real flexibility is with typography and colours.
Con Large font sizes
Con Archived
Git repo has been archived so it's pretty unlikely to receive bug fixes or new features.
Con Not widely used
A large community is always an advantage especially for open source projects. It means better documentation, continued development, and lowers the possibility for the project to be abandoned in the future since the probability for someone from the community to keep maintaining it is larger if the community is larger.
Con Single developer
There is no team developing this framework, except one guy.
