Note his sample size is around 4,000, which is ROUGHLY 20x what Ty's poll was. It isn't based on a 1-10 scale, but seems rather to be people saying which Jobs were their favorite.
Of note here I just wanted to pull from the healer section:
WHM: 29%
SCH: 19%
AST: 21%
SGE: 31%
He notes the comments have a fairly even split, but in terms of popularity, SGE > WHM > AST > SCH, which is interestingly more or less the opposite order people on these forums tend to rate the enjoyability/favorite-ness of the Jobs. (Not exact, but roughly), with the one exception of SGE being fairly enjoyable to everyone.
I'm not posting this as some kind of "gotcha".
I'm more posting this to point out the importance of sample. Who you poll is what's going to determine the outcome of polls.
Looking at the poll done here, it was basically SGE > SCH > WHM ~= AST. His poll was SGE > WHM > AST > SCH, with a larger sample size, but probably a different type of player. As he says when talking about Tanks (and why he was surprised WAR wasn't higher), he thinks his audience is more casual players.
(Incidentally, SMN also did FAR better under his poll)
It is true the polls were also asking for different things, but as I commented on Ty's BLM result, because he didn't limit it in any way (no requirement people answer for all Jobs OR limitation on their favorite), we ended up with cases of BLM being super highly rated, despite tons of people hating it, because the only people who rated it were people that love it for the most part. And as Alber points out, some Jobs (BLM in particular) have really stark love/hate relationships, meaning if the hate people aren't bothering with it, then it's going to have an inflated result (BRD and SCH were two others he pointed out).
.
The one big takeaway for healers - besides the importance of who is taking your poll - is that both groups seem to like SGE.
