Where the two actually differ on the specs we track (6 of 8). Matching specs are omitted.
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Only one whitelisted tester, Pro Tool Reviews, published a genuine hands-on review of this exact 2460-21 kit, and it is positive but qualitative with no lab benchmarks. They praised power, ease of use, price, and surprising run-time from the single battery, while noting the one-battery kit and material melting at full speed. (1 sourced review, 1 lab-tested.)
Praised: Power, ease of use, and value at a hobby-tool price; More-than-adequate run-time from the single RedLithium battery; Variable speed control (5,000-32,000 RPM) is a real asset for control.
Flagged: Kit ships with only one battery; At full speed it melts/burns some materials; speed must be dialed down.
