I'm pretty militant about stand setup, entry and exit, as far as scent goes. I've also been lucky enough to hunt on and own land in an area with lots of deer and very liberal tags. I've also been lucky enough to be able to hunt other states and in Canada. So, while not bragging, I've probably killed a couple hundred more deer than the typical hunter and, pardon the pun, I often buck the trend dejure or the conventional wisdom of the herd.
That said, while conventional wisdom is pro-rubber boots, I agree with the link about hating rubber boots. If you want hot sweaty feet or cold sweaty feet, that you can't wait to get out of after 3-4 hours, then rubber boots are for you.
Instead, I suggest the best and most comfortable boot you can find, albeit for walking or sitting. Comfort, be it for clothing or even a chair or treestand, translates to staying on stand and a more enjoyable hunt.
As far as scent, boots are only as good as how you store and wear them. If you wear rubber boots in your truck or on a quad, the gas from the mats and on the quad will likely get on the boots too.
Basically, if you enter a stand site the same way you expect the deer to come from, you're looking for trouble even if wearing rubber boots or even boy in a bubble suit.
If one wants to obsess about scent, and a serious deer hunter should, obsess more on everything related to stand setup, entry and exit and comfort and quietness of the gear.
I've seen lots of guys at my camp swear by rubber boots as essential, only to brush their teeth with minty toothpaste, when baking soda instead of toothpaste is what they should have worried about instead.
