Do you think keystonelearning's products or LearnKey's products are better to learn computer related things?

Have any tried both products and compared?

What are those? Never heard of them. Are they for a specific subject or like a set on various languages/OS's? I'm tired, and lazy... I'll do a search tomorrow. :) Someone might be able to give you better suggestions if you tell us what you wish to learn. ;)

Keystonelearning.com and Learnkey.com sell training tapes & Cdrom. I purchased a subject to learn from Keystone Learning once, and I pretty much liked it. I wonder which company out of these two has a better teaching technque. Like thorough & easy to understand.
