Short answer: the Dayton Audio CS1200. Both are rated 4.1/5 for sound quality (#9 and #14 of 212 subwoofers), and the Dayton Audio CS1200 costs $239.98 against $499.99 for the Monoprice SW-15, so with nothing between them on sound quality, price settles it.
What the Monoprice SW-15 does well: A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. Watch for: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.
What the Dayton Audio CS1200 does well: A budget 12 inch ported subwoofer with real punch for a mid-size room, remarkable output for the money. The tradeoff: At 38.8 lbs (17.6 kg) and 457.2H x 393.7W x 415.8D mm the cabinet is large for a budget sub and needs deliberate placement.
Buy the Dayton Audio CS1200. Both are rated the same for sound quality, and it costs $260.01 less than the Monoprice SW-15.
