Yeah, just another BSD fanboy. Move along.
apt-get IMO is in most ways (not all) superior to any "package management" on *BSD.
In the end though, it's all preference and administrator skill. Go with whatever you're more comfortable with, and know the most about. One will NOT outperform the other by any significant margin doing lowly tasks such as webserving.
On a side note, the BSD zealotism is getting a bit much lately IMO. It's like Linux zealotism back a few years. Ugh.
Everything has it's place, in this case there really shouldn't be much in-fighting. They both do extremely well in capable hands.
And no, I'm not going to get into the points this guy had more or less 100% wrong. It's just not worth it.
