.CH and .LI should be the first pick if you're buying in long term. .COM etc. are Verisign Corp (essentially US Gov) names and you're screwed if there's a global conflict down the line and want to be treated neutrally. I'm not tying myself to the future Montenegrin (.ME) administration or god forbid some fly-by-night meme gTLD run out of Hong Kong that goes bankrupt in two years and defaults on their ICANN payments, getting wiped from the root zone.
