The short answer
The Makita 9557PBX1 costs $78.01 more (170% more) than the AVID POWER AG589 — $124 vs $45.99. For the extra money you get: a paddle switch and a metal gear case. Meanwhile the AVID POWER AG589 has a tool-free guard, which the Makita 9557PBX1 doesn't.
Buyers rate them 4.8 vs 4.5 stars, and the Makita 9557PBX1 has fewer reviews behind its rating (3,975 vs 6,300). On our 100-point scale that works out to 93 vs 86.
Bottom line: if you'll use it often, the Makita 9557PBX1 is worth the $78.01. For occasional jobs around the house, the AVID POWER AG589 does the work for less.
