It's a pissing contest of titanic proportions. The NTC did some benchmark tests on the services of the two biggest telcos and came up with some unflattering results. (If you want to check out a balanced report, click the link for one from Rappler.) Globe and SMART both reacted strongly to the tests, which you can also read in the link. My reaction is summed up by the somewhat blurry meme above, which I found on Facebook. But you get the idea. As the Alma Moreno saying goes, damage you do, damage you don't.
