I've used both Element 3D and Invigorator Pro in my workplace (I get a few hours a day to play on a colleagues PC!). For me there is absolutely no contest. 3D Invigorator is by far the better product. It's just a pity that Invigorator Pro is so expensive. If it were $200 less I would buy a copy to use at home right now! Version 6 looks awesome! It's such a shame that it's priced out of the range of hobby enthusiast like me. I really love the product, and I recommend it to lots of people, but I can't justify spending $500 in the current financial climate. Still, if anyone has the money and can't decide which to purchase, get Invigorator Pro. You won't be sorry. :)
Thanks for your comments! Both are great products to use in After Effects but we've been getting users who have been telling us the same story and we're really proud of all the work that we've put in for both 3D Invigorator PRO and ProAnimator.
