I highly recommend that you just cut the middle man and go directly to the original sources yourself. Relying solely on TFwiki simply won't do justice to the level of depth of the answers that you seek. It's kinda like trying to understand a book or movie by only reading summaries printed on the back of the book or DVD/Blu Ray case... nothing really quite beats actually reading and watching the original sources for yourself.

That way you'll have all the information you need and it will be first hand, not second hand (which is never as reliable as obtaining it first hand). You won't need to worry about the personal opinions of anyone else "diluting" the information. I feel that it would be in your own best interest to go and read/watch the source materials yourself if you truly want an in-depth understanding of Transformers lore presented to you without third party bias.
