The benefits of using a lightweight web browser includes faster performance like faster website loading times, more free RAM, CPU, and storage resources for doing other tasks, better reliability, lower power consumption, longer battery life, and no un-needed features. Some lightweight web browsers are also easier to use because lightweight web browsers user interfaces are very basic with just the features like tabs, bookmarks, address bar, and navigational bars which most users need to browse the web.
The greatest advantage of using a Lightweight Linux Web browser like Midori on a Lightweight Linux Operating like Raspian is that you can browse the web at a good speed even on less powerful computers like the Raspberry Pi 1-2, or an old desktop, netbook, ,laptop, tablet with a 800-1000 Mhz single core CPU, 256MB of RAM, and 10GB or less storage. You can re-use your old computers or use a cheap low power usage Linux PC like the $35 Raspberry Pi 2 for browsing the web at a usable speed when using a lightweight web browser like Midori. Using Midori, Web, IceWeasel, and Firefox on more modern Linux computers would make browsing the web very fast, and responsive because of the low system resource usage of Linux based operating systems like Puppy Linux, Linux Mint, and Debian.
I like having Kweb/Minimal Kiosk Web Browser, Midori, IceWeasel, and Web/Epiphany web browser installed on my Linux computer since sometimes some websites work better on Midori, and Web, but other times IceWeasel displays websites better. There are also different add-ons, features, and plug-in support which only work on IceWeasel, Web, or Midori, so each web browsers have different purposes for me. I like using Web to watch online video because it is the only web browser which I know of which supports hardware acceleration for online videos, so they run smoother. IceWeasel is compatible with a lot of Firefox add-ons like password managers, website file downloaders, IRC Chat and web development tools. Midori is a minimalistic web browser with nice features like a user agent changer to change the website layout to a mobile iPhone site which is useful when I want to view the mobile site instead of the desktop site.

IceWeasel and Firefox
I usually use Firefox on Ubuntu, Linux Mint, and other Linux Operating Systems which comes with Firefox pre-installed, or has Firefox in the Software Center. There is currently no version of Firefox for the Raspberry Pi, so you have to use IceWeasel which is based on Firefox. Newer versions of Firefox seem to use less RAM, and run more smoothly. Firefox always seem to run smoother on Linux because of Linux’s lower RAM usage. Firefox runs pretty reliably in Linux Mint and Ubuntu when I use Firefox in Linux Mint and Ubuntu. Firefox rarely crashes, or freezes in Linux even when I use Firefox on an older Linux PC with an AMD 1.7 GHz Single Core CPU, 256MB of RAM, and 60GB of hard drive space. There are a lot of nice extensions, add-ons, plug-ins, and features in Firefox which make it nicer to use by adding more features to Firefox.
Midori is a simple WebKit based web browser like Apple Safari browser and Google Chrome. It has most of the important features like tabs, private web browsing, History bookmarks, spellcheck, RSS feeds, fast file downloader, HTML5 support, support for plug-ins like Flash and Java, and Downloads manager. Midori comes with Extensions like colorful tabs, cookie manager, copy address of tabs, feed panel, etc which you can turn on or off in the Preferences section of Midori under the Edit Menu on the Menu bar. Midori has a lot of useful settings like changing the useragent to iPhone, so it loads the mobile site which is good if you use Midori on a slower PC, or tablet because mobile sites load faster than desktop websites. I can also turn off images, scripts, Netscapte plug-ins like Flash and Java, and turn off spellcheck on Midori to make websites run faster, and more reliably on Midori. When I use Midori on my Raspberry Pi mini computer, Midori load websites like Reddit, Twitter, and Google. Midori also scrolls up and down most websites smoothly. Midori is also okay for playing 360P video on YouTube in my experience when I use Midori on my Raspberry Pi 2. Midori is reliable, and does not freeze or crash a lot. I like the simple user interface of Midori. There is a title bar, menu bar, bookmark sidebar, bookmark bar, address bar,Status bar, navigational buttons, search box, tab bar which is hidden when only one website is opened. It is easy to hide unwanted bars like the status bar, bookmark bar, and menu bar in the View menu under Toolbars in Midori. There are very little un-needed features like visual effects, pictures, and animations on the user interface which can slow down Midori.
