Have you tried fixed windowed mode? It’s what I use. And, I use Kuroro Lucifer’s Autohotkey script in order to rearrange my clients. He also provides .ahk files (which can be edited with notepad), which you can use as a template for creating your own specific layouts with your preferred hotkeys.
Anyway, this allows me to place my clients exactly where I want. No titlebars, no borders, and no taskbar overlapping my windows/eating up screen real estate.
