Most of look and feel in Linux is the desktop program, not the distribution.
I'm not sure what desktop you had with Debian, but my best guess is it was gnome.
I like KDE much better than gnome (I think the several other available desktops are worse than gnome).
I like the Mepis distribution best. In small part because it has KDE as its initial default desktop (though you could also easily change to KDE in some other distribution). Mepis is slightly more beginner friendly than other Linux distributions in a few other ways as well.
Mepis is available in 32 bit or 64 bit liveCD (same .iso image is both liveCD and installer, which is another convenience common to many, but not all, distributions).
I don't think any distribution is particularly "optimized" for 64 bit. Many distributions (such as Mepis) are available compiled for x86_64 architecture. Obviously if it isn't available as 64 bit, it isn't "optimized" for 64 bit. But among those that are available in 64 bit, none are significantly more optimized for 64 bit than others.
Mepis is a free download and access to its repositories are free as well. The web site encourages buying it instead and makes it a bit less obvious than typical free distributions that buying it is optional. I don't mean to discourage anyone from buying Mepis. But if you aren't willing to purchase Linux, I don't think that should stop you from selecting Mepis.
