The ranking is rather Vodafone, T-Mobile, O2 and after a huge gap eplus.
eplus is still a discount network with an inferior network, that regularly suffers from congestions making phone calls impossible and data over the eplus-network is a total mess, too.

@Kritiker
I would recommend a Fonic SIM for your purposes. Getting a Fonic SIM in Munich is a question of minutes. For further information on Fonic see Germany - Fonic - Prepaid Wireless Internet Access
