Elixir will leave the more durable protection. EcH20 will leave more protection if the concentration is higher say when used as a waterless wash. As a drying aid/detail spray it will last until the next wash. To answer your question yes Elixir is that good. At least I think so. I actually like both products. I use EcH20 more often then not and on occasion I will use Elixir.
If you want to save some money you can make your own elixir mixing up EcH2O and Reload.
