1 seconds discussion: iTeXMac or TeXShop ?

• Do you really have to choose? why not have both?
• No serious comparison has ever been made between both.
• Don't believe people saying TeXShop is the best: they don't know iTeXMac.
• Don't believe people saying iTeXMac is the best: they don't know the forthcoming version.
• But hey, why do you think there are still many people using OzTeX, TeXTures, TeX Tools and so forth...
• Anyway, iTeXMac IS the best.
• You are free to believe me or not.
