Every comparison follows the same structure: quick verdict first, then a scored head-to-head table, then detailed pros for each system, then FAQs. We score the same five dimensions — equipment, monitoring, value, setup, support — and clearly state who wins each category and why.
We don't pick favourites based on commissions. If a brand loses a category, we say so. If there's a genuine tie, we say that too.
