How long a list do you want? I did extensive research into Maya and their competitors prior to making such a sizable monetary investment. It may not be a lot of money to some ppl, but for me it is. I am retired so time was/is not a problem. It depends on your goals and willingness to invest in those goals.
There is a plithoria of reviews by knowledgable professionals and enthusists available. Most agree, Maya has a high learning curve, however most also agree that it is a matter of trying various programs (demos are available for most) and making a personal comfort decision. I skipped this and dove immediately at Maya because it encompasses so very much and the creative possibilities are seemingly endless.
I realize mention of competitors on this site is understandably forbidden, however - I have invested in ******, but look where I am. I have found that while ****** is awesome, for me, this is better. I have a great respect and appreciation for the efforts and results driven ideology of this site, the awesome community, and almost instant response to any and all inquiries without the customary denigration. You do not find that elsewhere. This is fact, not speculation.
Just mho.
