I bounce between Sol high/medium and Luna max. I don't know why you'd use anything between Luna max and Sol medium. Luna is so extremely cheap and cranked up to max it does anything I'd want Terra to do for a fraction of the cost. What is Terra for?

One thing I've really noticed with Luna Max is its speed. I've got a review script setup on a custom Pi extension. Luna finds some issues/some false positives, while Sol finds issues but disregards false positives. The biggest thing is Sol finishes in about half the time.
