Second the experience about better focus while sitting. But I prefer to stand for a while (~30min) when just arriving at work, coming from a meeting, or back from lunch. It helps me stay "active and focused" on taking control of what I'm doing ... which is super for making sure I get started with actual work rather than drifting off onto some lazy web surfing or whatever. And then, after getting properly into my work (opened the IDE / tmux/vim setup and started to code), I tend to slip down in my seat pretty quickly, to get into proper un-distracted focus. Getting back to standing mode occasionally if getting too drowsy etc.
