well, lxterminal is very...plain. I like transparency, I look a huge font database...you know, just change the tangible behavior.
Eterm is pretty darn sexy (supports transparency, etc.) but it can be a bear to install, if all the dep packages are not in the repo of your distro.
personally, my fave is urxvt. it is light-weight (versus gnome-terminal, etc.), yet very customizable. I install that and some good TrueType fonts w/hinting (Liberation Mono, Bitstream Vera Sans Mono), put some quick customizations in my .Xresources file, and i'm happy.
