I didn't feel like Strip Search was a
particularly effective way of finding
the best cartoonist in the group.
Typically for reality competition shows the goal is to produce programming that draws in viewers, rather than to find the best competitor.If 'survivor' wanted to make a show about survival skills they'd use a bunch of ex-marines, mountaineers and woodmen. If 'dancing with the stars' wanted to show the best dancing, they'd get rid of the celebrities and just have professionals. If 'the apprentice' wanted to find people with business skills they'd get candidates smart enough to realize infighting isn't a useful business skill.
I'm not saying I like it, but 'so you think you can dance' certainly has more viewers than the Prix de Lausanne youtube channel. And what's the point in making ideologically pure TV that no-one wants to watch?
Dancing with the Stars finds the best dancer out of the group, even if they're not pros. Survivor ostensibly finds the best survivor out of the group, even if they're not true outdoorsmen.
Reality TV is the same - except the fiction is the competition isn't rigged and its primary goal is to find the best candidate. The show doesn't wildly contradict it, it's just not true.
Looking at the strips after the fact, Abby and Katie pretty obviously are writing the best strips. And sure, Abby's is the better of the two, but her concept is harder to distill down to its essence and present - Katie was the only one of the three finalists who was able to competently and interestingly introduce her new strip with just a few sample pages.
If you think they picked wrong, who should have won instead?
(Note that several of the other cartoonists have been hired by Penny Arcade for other tasks such as doing The Trenches and designing pins. So even if you ignore the publicity aspect there were still multiple winners.)
Of the last two, Abby should have won IMO.
That's a very different type of challenge from "You can't dance, and we want to see if you can learn to dance before you explode", and that's part of why SYTYCD is a good show. Obviously it's a reality show and SYTYCD is going to have some compromises (for example, you might argue that the judge selection is suspect, or that the styles and choreographer choices are limited) but it was honestly pretty close to ideologically pure as you could get; the people who succeeded were the people who were good at dancing, not the people who were good at ballet or contemporary or hip hop or ballroom.
On the other hand, I can't see an ideologically pure version of 'So You Think You Can Code' any time soon.
