Evidence before recommendations

We compare exact products, versions and buying situations. Our conclusions explain the conditions that favor each option, including when keeping what you already own is the better choice.

Research means a source-led comparison. Partial Test means only part of the comparison has been tested under a recorded protocol. Full Test requires coverage of both products and the decisive dimensions. Manufacturer specifications and third-party tests are never presented as our own measurements.

Conflicting, outdated and missing evidence stays visible. A rebuild does not count as a fresh review. Sources and substantive review dates accompany each comparison.
