Have you ever seen these internet browsers?

[someone_else]

Some day ago I was installing XP as a Virtual Box's virtual machine in my Puppy Linux Lighthouse, and I noticed that when the usual "choose your internet browser" window popped up there were various new browsers I have never heard anything about (after the usual IE8-FF-Op-GC).

Lunascape Browser "LUNASCAPE is the world's first and only triple engine browser. It has been downloaded over 20 million times and it's available globally in 12 languages. Try it for yourself the new kind of speed and versatility. "
Sleipnir browser they say it is popular in japan, and that it uses the trident engine, the same as IE.
K-melon "K-Meleon is an extremely fast, customizable, lightweight web browser based on the Gecko layout engine developed by Mozilla which is also used by Firefox. K-Meleon is Free, Open Source software released under the GNU General Public License and is designed specifically for Microsoft Windows (Win32) operating systems."
Maxthon browser that they say is super-fast and has cloud services for bookmarks and stuff
Avant Browser which has tons of integrated features, but they say is faster and lighter on memory than anyone else.

Now, what I'm asking is: what the heck are these? Anyone tried some? Anyone liked them? Opinions on them?

And also to keep you informed.

I'm familiar with K-Meleon. It's an extremely lightweight Firefox-alike.

Avant's what I used to use before Firefox came out. Its main draw back then was adding tabbed browsing, ad blocking, a download manager, and a host of other features to IE6, but I have no idea what it offers over vanilla IE now.

I've heard of Sleipner, but only because it became a hilarious joke amongst me and some friends (classics A-level!)

I used Maxthon before Firefox, liked the tabs feature.

I used K-Melon back in 2004-2006. It was essentially Firefox Lite. If someone ported it to Android I can see it as a powerful alternative to the bloated FF.
