Short answer: the Infinity IL10 for better sound quality, the Dayton Audio MK602X for the lower price. The Infinity IL10 ranks #54 of 84 bookshelf speakers at $160. The Dayton Audio MK602X ranks #83 at $149, $11 cheaper.
What the Infinity IL10 offers: Impressively flat for a budget bookshelf. Watch for: Resonances at 600 and 5khz, which show up as distinct distortion spikes at 96dB SPL/1m in the same frequency regions.
What the Dayton Audio MK602X offers: Inexpensive, compact two-way with a 6.5-inch glass-fiber woofer and 1-inch silk dome. Watch for: The top end sits roughly 5dB above the midband, producing brightness that can masquerade as detail.
Buy the Infinity IL10 if sound quality matters more than the price. Buy the Dayton Audio MK602X if the price matters more than sound quality.
If sound quality matters at all to you, skip the Dayton Audio MK602X. It ranks near the bottom of the 84 bookshelf speakers, so look higher up the list instead.

Infinity IL10: $160 used, Discontinued
Pros: Impressively flat for a budget bookshelf. Predicted in-room response is good aside from a bit of excess energy here and there. Distortion at 96dB SPL/1m stays low and controlled outside two narrow resonance-driven peaks.
Cons: Resonances at 600 and 5khz, which show up as distinct distortion spikes at 96dB SPL/1m in the same frequency regions. Discontinued.

Dayton Audio MK602X: $149/pair Amazon Parts Express
Pros: Inexpensive, compact two-way with a 6.5-inch glass-fiber woofer and 1-inch silk dome. Erin measured respectable small-box extension—72Hz F3 and 43Hz F10—and roughly 85dB sensitivity. The cabinet and removable grille are tidy for the price, and the response can be made less bright with broad treble EQ when listening close to the reference axis.
Cons: The top end sits roughly 5dB above the midband, producing brightness that can masquerade as detail. More seriously, the low-order woofer filter creates a 4-5dB directivity discontinuity around 2kHz; because the reflected sound differs from the direct sound, equalization cannot fully fix it. Erin also found multiple resonances around 900Hz and rising distortion/compression from the woofer at higher levels. Its 4-ohm nominal load and modest 85dB measured sensitivity demand more amplifier current than the price suggests, while the 72Hz F3 makes a subwoofer advisable despite the relatively low F10.
