The independence was a higher end gun that jack made for a few years. It's made in the USA 100% so it has higher tolerances for more precise operation. It's also older than the invasion.
You're right though, at a glance there isn't a lot of difference. The invasion was made to be more economical. Plainer milling, parts made in asia, a few other minor plumbing differences. Plus the macroless design since it's a later design than the indy.
They're both great little shooters though.
