Compare the battery lanes before you buy the tool.
Comparison pages are for high-intent platform decisions: which battery lane fits the next jobs, where total cost hides, and which adjacent hub or brief should guide the next click.
Compare 2-4 battery lanes against your actual garage.

Comparison constraint: keep 2-4 lanes. Exact-model prices and observation counts can support timing context; platform-level evidence cannot be promoted into an exact-model performance claim. Planning totals use explicit battery, charger and replacement reserves, not live-cart or resale guarantees.
DeWalt vs Milwaukee: which cordless platform should you buy?
DeWalt 20V MAX is the safer mainstream lane for broad DIY and trade-adjacent coverage; Milwaukee M18 is the pay-up lane when duty cycle, FUEL depth and heavier expansion justify the cost.
Milwaukee M12 vs M18: which battery platform should you buy?
M18 is the power-depth lane; M12 is the compact-specialty lane. Treat them as separate battery decisions, not one interchangeable Milwaukee platform.
Makita LXT vs XGT: should you stay 18V or open the 40V Max lane?
Makita LXT is still the safer mature 18V lane for most owners; XGT only starts to make sense when repeated high-demand work justifies another charger, battery line and price-history watchlist.
Ryobi vs DeWalt: which cordless platform should you buy?
Ryobi ONE+ is usually the lower-cost DIY lane; DeWalt 20V MAX is the pay-up lane when duty cycle, upgrade path and battery depth matter.
