Best international keyboard layout?

Hello,

I'm trying to pick an international keyboard layout that is as close to US as possible, while allowing me to type letters for european countries. I've narrowed it down to three options, all offered by linux by default:

• altgr-intl - English (intl., with AltGr dead keys
• altgr-weur - English (Western European AltGr dead keys)
• EurKEY (US)

Does anyone use any of these and maybe has some recommendations on which to use?

Maybe I've missed some other obvious option?
