Yakuake. You're easily spoilt by a quake mode terminal and it's hard to go without it. Tab management and shortcuts are great. Full utf8 support.

It's essentially the same as Konsole, all the internals are shared libraries.

That all said, dunno how it would fly with a tiling window manager.

I use Yakuake with the Awesome tiling window manager and as long as you add it to the rule for floating clients in your rc.lua it works perfectly.
