Personally, I think a thread dedicated to saying which store we like better just adds to the "fanboyism," and it makes me want to put a torch to my lap top so I don't have to read garbage like this. (Obvious exaggeration, but you get the point.)
I enjoy E's cards, and I enjoy T11's cards. Would I use them for performing? No. These cards are too expensive for me to use in performance. I may use them to practice for some eye candy, for Cardistry, or just for my collection.
As for comparing the amount of magic from each site, E obviously has more. Of course, E has been around for a few more years than T11. T11 has only been around for a little more than two years. It's not even that old. Not only that, but E has been selling some productions from different magic companies. They have some stuff from Papercrane, De'vo, and a few other companies.
Final Verdict - Who really cares? I get what I like. I have no preference. If E comes out with something insanely awesome, I'll get it. If T11 comes out with something insanely awesome, I'll get it. I really couldn't care less. I'm not a fanboy. I'm not going to only buy things from T11. If you are a fanboy in magic, you need to get a life. Very simple. Unless you have a personal reason (such as maybe bad customer service), there is no reason to say "I support T11 more than Ellusionist!" unless you are just a whiny fanboy who needs to get some friends, and stop taking magic companies so seriously. Seriously, you're on a magic forum. You don't even know the people who are making these projects personally. You only know them by what you see of them on their website. I almost crack up whenever I see someone make fun of Brad Christian on this site, because he's better than 90% of the people here, yet all I see is comments about him wearing eyeliner in one of his DVD's. Yup, you got him bad.
