Gulp vs Lineman

Currently gulp offers a selection of 1000+ plugins and it is growing rapidly.

This depends on your style, but gulp is closer to the code, the actual execution isn't hidden by multiple layers and it's much easier to customize the build system without writing bloated modules. This also brings rather small configuration files.

Any task can be set to have other tasks as dependencies. The dependencies are specified through piping streams, and tasks run concurrently if they do not block in dependencies.

Since Gulp just uses streams at its core, you don't actually need a plugin wrapper to use a project that uses streams. If you use this approach, the you don't even have to worry about plugin maintenance at all, and get the bleeding edge updates as soon as they come out even if the plugin hasn't been updated. It also means if a project happens to not have a plugin, you don't need to write a new one, you can just use it as is.

In gulp, it's easy to pipe multiple steps together which you commonly need with build systems. For example, you may need to compile the javascript source files, then package them together, and then minify it. The streaming system makes this much easier.

Additionally, it improves performance since all operations are done in memory (compared to I/O operations) and avoids the need of unnecessarily compiling files (compared to Grunt that has to compile all files even if just one has changed).

In Gulp, the transforms are performed through chains which makes it easier to understand the order of operations, and easier to modify it.

Because streams in Gulp use pipes to establish dependency order, they are parallel by default without having to rely on plugins or hacks.

Because Gulp is built using streams, it can store intermediate transformations in memory and defer writing to disk until the very end. This improves performance by not requiring expensive blocking disk operations for task dependencies.

Gulp's configuration file is actually very readable because it's actual JavaScript instead of a large file of JSON objects. The entry barrier is very low for developers who have never used a task runner before and it's API is very simple, with only 4 methods.

Because Gulp is built on top of the streaming API, you don't actually need gulp to use them. This could be helpful if you want to re-use those modules outside of gulp, possibly for testing, and using the same modules would be more consistent.

Lineman integrates a powerful test runner - Test'em. By default it will test against PhantomJS and output in TAP13 format.

While Lineman is hands off when it comes to what you do on the client side, the workflow and tools used around it are opinionated, which means there's less to set up, the tools picked are fine tuned to work together, and you can get up and running faster without having to decide between dozens of tools. While it means less flexibility with the tools you use, it also means that advanced features are built in and available from the start, and you can focus on building the client side, without worrying about the tools around it.

Although Lineman is fully configurable, it comes with well tuned defaults and a built in scaffold so you can get up and running with advanced features quickly with things like continuous integration and live reloading with less or no configuration.

Lineman prides itself on avoiding assumptions on how things should be done and allows for greater freedom in tool choice. It generates a skeletal app, with no example code. Yet if you choose, you can get templates for Backbone, Ember, Angular and other frameworks.

Lineman is designed against code generation, which is a good thing as generated code requires more maintenance to keep library code in sync with the generated code, and is dangerous to use if you don't fully understand what the generated code is doing.

While the tools Lineman uses are opinionated, the build process is not as it uses Grunt, so you can get the benefits of a well tuned workflow while still being able to use whatever compiled languages and build process you want. Also, since Lineman handles the tasks outside of compilation and file transformation for you, you can keep your gruntfile simpler and easier to maintain as it would be dedicated to just the build system, and not other task management.
