Lots of things can be taken into consideration when looking at DRAM bus voltage. Generally, the lower voltage the better because of decreased heat and power consumption and possibly increased overclocking headroom.
That said, given that the kit you are looking at is rated for 1.5V or less I feel that there are more important things to look for, being:
1. Frequency
2. Latency
Get the kit with the highest frequency and lowest timings you can get within your budget, take voltage into consideration when buying RAM when say you find two sets with nearly identical frequencies and timings for the same price but the two sets are rated to run at different voltages, then opt for the lower voltage kit.
Realistically temperatures aren't significantly impacted by voltage when considering kits that are rated for 1.65V or under, especially considering the types of heatspreaders we are seeing on RAM nowadays. And there isn't really a justifiable decrease in power consumption to pay more for a low voltage kit. Heres an interesting article on Tom's Hardware about it:How Much Power Does Low-Voltage DDR3 Memory Really Save?
So really it comes down to having more OC headroom, and even that varies from kit to kit. Some scale very well with a little more juice and some don't budge (1.25V G. Skill SR-2 Snipers for example).
Just my 2 cents
