Baofeng UV-25 vs Retevis HA2

The Baofeng UV-25 is the clear winner here. It scores higher overall, costs half as much, and offers confirmed 10W transmission power versus the Retevis's unknown specs. The single most important differentiator is price-to-performance ratio. The UV-25 delivers superior value at $50 with full CHIRP programmability and GPS capability, while the HA2 costs twice as much with fewer confirmed features and no CHIRP support.

The UV-25 suits budget-conscious operators and those who prioritize programming flexibility and built-in navigation. The HA2 appeals only to users who specifically need APRS functionality and don't mind paying a premium for it.

Unless you have a specific operational need for APRS and can verify the HA2's power output meets your requirements, the UV-25 is the smart choice. It's cheaper, better reviewed, and more versatile. The HA2's incomplete specifications and higher cost make it difficult to recommend without more transparency on TX power and additional features.
