No, they are not.
The legal title to a property is something that exists permanently with any property and its owner, so if you got up now and went and bought a sandwich and a drink from somewhere you would hold the legal title to those products.
Say you then decide to give the drink to your sister, but decide she's not old enough to have full responsibility for it yet so declare your Mum a trustee of the drink for your sister. At this point the legal title for the drink is passed to your Mum but your sister now has an equitable title in the drink. This equitable title is created by your making of the trust. Your Mum now keeps the drink on trust for your sister, and thus must not 'enjoy its benefits', which here would mean drinking it. After a period specified by you the drink is handed to your sister and she gains the legal right, and the equitable right disappears.
Obviously you wouldn't do this for a drink but here's a more plausible real life scenario:
Joan and Bill have 2 grandchildren, siblings, both below 18. They want to leave 10 thousand pounds each to the grandchildren should they die but only want them to have access to it once they are adults. At this point only a legal right, that of Joan and Bill, exists in the money. Thus they create a trust in their will that if they die the legal title for the 10k will transfer to the grandchildren's Mother but the grandchildren have an equitable title in the money. This equitable title means the mother cannot use the money for her own purposes and all benefits of it, notably interest accrued, are to be kept for the grandchildren. Again, once the legal right passes to the grandchildren the equitable right vanishes.
Trusts are used in commercial settings, see cases like 'Re Kayford' (1975) and Farepak Food and Gifts (2006).
Also, worth checking out the introductory chapter of an equity textbook.
