Should Gamepress retire the Raid Guides?
I've been following Gamepress for since July 2016 and find their guides very helpful. Their best breakthrough is the DPS/TDO Rankings for quick references for best counters. However their raid guides are not accurate. It stats that Motlres and Entei are the best counters while Machamp and others are only "good." This is misleading because it does not take into account weather and movesets "probably don't want to use Entei against Earthquake" Take a look at the attachment.

Regice is just weak to several strong types (fighting, fire, and Rock), and so makes the guide look bad.
When you look at DPS and TDO, the Pokemon are all pretty close. It shouldn't be a big surprise that weather is a big enough factor to change optimal counters.
I think the guide is still useful, to help identify which Pokemon should be candidates.
I'm assuming your question is referring to Regice?
The main point of difference I think is that your attachment charts are all ranked by DPS, which is fair, and what a lot players want. But their description of Supreme Counters includes "high survivability", which Machamp doesn't have, at least compared to legendary bulk. That and with the current revive/potion drought I think TDO factored more heavily into their decisions.
But whichever is better depends on your playstyle of course.
Anyway the Raid Guides and the DPS/TDO calculators serve different purposes on the site. If someone, say a casual player, wanted some recommendations they'd pop over to the raid guide rather than have to fiddle with the calculator and numbers and different settings they don't care for or know what to do with.
