The bottom line is BOTH the non-ESA and the ESA shocks are a huge improvement over the stock shocks. Whether you want to or need to upgrade to the ESA version is a personal choice, and a choice you should base on your riding style and needs.
Talk to someone who's in the suspension business, not your local dealer. Find someone who is willing to give you 15-20 minutes to talk about you, your bike, your riding profile and your expectations from the upgrade.
I have yet to hear anyone who upgraded to either of the Ohlins products say they were unhappy and I expect you will be happy with either as well. As I said, for me, the non-ESA models were the right fit for my style and expectations.
