I would suggest not to rely completely on their answers regarding the 3G coverage. I sent the same request in all three companies, a couple of months ago regarding 4 locations in Greece. For 2 of the 4 locations, all three operators replied that there's no 3G coverage, and I had 3/5 to 5/5 3G signal with all three operators!
The best way to be sure is first to check for yourself if there's a good 3G coverage on your location and then to buy a prepaid card/plan from the operator that has the best signal. 3G signal is a wild beast and it can change a lot given the geomorphology of Greece.
Also, to my experience and that of many others, Vodafone provides absolutely the fastest 3G speed and latency (usually 2-7Mbps), then is Wind with (1-2Mbps on average) and last Cosmote (with 1Mbps). However, Cosmote provides the widest 3G coverage across Greece, however their speed suffers and could be as low as 20-30kbps.

The two plans you are quoting are not prepaid but postpaid with 12-24 months contract.
To check for the prepaid plans, you can have a look on my recent overview on the sticky thread about Greece on the top.
