According to speed benchmarks, Brunch is one of the fastest tools around for compiling files. According to the authors of Brunch the reason behind this speed is that it recompiles **only** the changes that were made to an app and performs extensive caching of the app's code.

Pro Compilation is super fast
According to speed benchmarks, Brunch is one of the fastest tools around for compiling files. According to the authors of Brunch the reason behind this speed is that it recompiles only the changes that were made to an app and performs extensive caching of the app's code.
Pro Time to setup is extremely low
After installing Brunch the next step is to load a skeleton from git.io/skeletons. This step is as easy as installing another plugin from the npm registry, just point Brunch to the path of the required skeleton/generator then wait for it to work out its magic. Next, run
brunch build then wait for a second or two and voila! the project is ready.
Pro The configuration file is small and the configuration itself is fast and easy
Brunch's config files can be extremely small compared to other alternatives. The fact that brunch also allows you to chose from a number of generators also lowers the configuration time considerably.
Pro Concatenates scripts and styles and auto-generates matching source maps
Pro Registry agnostic
JSPM is registry agnostic, it can pull packages from npm and github and is built in such a way it can support more.
Pro Versioned package urls
It creates a packages folders which are versioned. This makes it future proof for a time where we stop bundling all the code. In the following presentation Guy Bedford calls bundling an anti-pattern.
Pro Switch between async or sync load
With a simple command you could change between load the modules async by systemjs or sync with a bundle file.
Pro Much faster than Webpack or Browserify
While Webpack and Browserify recompile the source code using Babel, jspm is the only packager that can load prebuild/minified code downloaded from the npm registry.
Pro Module style agnostic
Loads ES6, AMD, CommonJS and globals.
Pro Can transcompile ES6, JSX and Typescript
Pro Bundled based on imported modules without any config
Create the bundle file without config and add only the modules imported.
Pro Easy install packages from npm, github or any git repository
Pro Very easy to start with
Con You need to be an expert to write shims
You can load any module. But that comes with the price:
you need to find or write configs to load a particular rare module.
Con Watcher has bugs
Watching would benefit from improvements
Con Unstable API
0.17 is still in beta. 0.16 is lacking features.
Con Poor bundler performance
Bundling performance is slow, though offset by the fact that bundling is not required during development, since it can load dependencies asynchronously.
Con Doesn't hide complexity
JSPM doesn't try to hide complexity from the user. I.e. when some issue emerges you need understand a lot to be able to patch it or create a workaround.
