I have had both and I think they're about the same except one issue I have. The Open Run sometimes just won't charge even though the charging light is on. I'll pick them up after hours and it'll say "Battery low". It's annoying. I also wish double tapping the button didn't dial the last number because it's too easy to do.

Some of the older programs and scripts I've seen in the codebases I help maintain have -u or -?. If I have an excuse to do any changes to them I'll usually change them to use -h and --help.
