I've put together a pseudo-guide on battle form stats. It's entirely spreadsheet-based and designed to provide quick visual comparison between battle form options, (mostly) broken out by similar stat groupings (attack bonuses, for example). I don't have it broken out by spell tradition type, but there are indicators in the column headers of which spells are available for which traditions. There's significantly less commentary in this spreadsheet set than in my other guides because the format is built to impart information without having to read much in the way of text blocks. The only real blocks of text reside on the landing page, which is designed to provide guide orientation, and in notes/amplifications below the main body of each sheet.
