It is nothing but IE's core with a different frontend interface along with extra features. If you are on the lookout for some different browsers, then yeah, do try it out.
Avant and Maxthon are two IE based browsers you should try out.
Flock, FF3 based, is one which you should try out if you are into social networking and such sites. Atleast give it a visit on www.flock.com for a unique browsing experience.
A friend told me to try Avant out so I did, but all it is in reality is IE under another guise, so if you're using IE stick with it. I use Firefox with the IE tab so I get the best of both worlds. Really it is a matter of **** and see, and if you dont like it as I dont with Chrome just remove it and go back to what you know and trust. There is one warning however, not all browsers are as safe as IE or Firefox so back up before you try and do a complete scan before and after
I have been a Maxthon user for quite some time now. Avant & Maxthon are basically IE based "feature-rich-shells". I found Maxthon to be better of the two.
there is one thing, many forums, networks iam on, no one has avant nor maxthon..only safari, IE, FF , chrome and opera. ill be first to use if decide on using avant or maxthon
