Lancelot and Kickoff

Lancelot's benefits

More powerfull search capabilities

In the beginning, Kickoff had very limited searching capabilities that couldn't be even compared to KRunner and Lancelot. This was changed in KDE SC 4.4 when code from Lancelot's search was ported to Kickoff.

Still, although Kickoff now uses the same engine for searching as Lancelot, since it runs in the same process as the desktop itself, most data providers (called runners) are disabled to prevent unstable ones crashing the whole desktop. (even the calculator is disabled)

Lancelot runs in a separate process, so it can handle the risk of using potentially risky runners thus providing all the features KRunner itself does.

Application browsing

When browsing application tree in Kickoff, you can only see the currently open category, and to return to the previous one you need to click the 'back button'.

In Lancelot, you always have an overview of the previous levels you opened while browsing, and in addition, you have a breadcrumb bar.

Logout and related options

In Lancelot, options for Logging out, Switching users etc. are accessible the instant you open the menu. In Kickoff, those are located in a separate section.

Devices

Lancelot provides quick access to both removable and fixed devices.

Better Plasma integration

Apart from the look and feel which is completely Plasma themed, Lancelot sports a few other integration points from bot developer's and user's perspective. One of the trivial examples is that Lancelot can be used as a 'Add widgets' dialogue alternative.

Lancelot's disadvantages

Spacial requirements

Although the initial sizes of Lancelot and Kickoff don't differ that much, making Lancelot's window smaller would render it barely usable which is not the case with Kickoff.

First impression

On the first start, Lancelot looks more complicated compared to Kickoff - two-columns plus section buttons versus one column that Kickoff sports.
