The short answer to this question would be that it is slightly better than it's O5e counterpart.
1. Every class in A5e and O5e can pick up Two-Weapon Fighting and wield two weapons in either hand.
2. The weapon in your dominant hand, however, no longer has to have the Light weapon property (O5e) or the Dual-Wielding weapon property (A5e). As long as it doesn't have Heavy weapon property, you can wield a d8 weapon in that hand.
3. The weapon in your off-hand still has to have the Light weapon property or the Dual-Wielding property for Two-Weapon Fighting to work.
4. Two-Weapon Fighting still requires a bonus action for your offhand weapon, but if you belong to a class that has the Extra Attack feature, you can use your bonus action to make two attacks instead of one. I consider this A5e feature to be an improvement as Two-Weapon Fighting in O5e became pretty lopsided once you got past 5th level. From 1st to 4th level, you could make 1 attack and 1 bonus action attack. Action Surge in O5e would just give you two attacks and 1 bonus action attack. From 5th to 11th level things were still okay in O5e as long as you didn't use Action Surge for the attack action. But once you got past 11th level, things became pretty lopsided as you would be making many more attacks with your dominant hand and just one bonus action attack. You would need a homebrewed feat at this point to balance out the number of attacks you can make with each hand.
With the loss of a third Extra Attack and Action Surge for the A5e Fighter and the tweaking of the bonus action attack after 5th level, the number of attacks you can make two weapons doesn't feel so lopsided as it was in O5e. An 11th level Fighter using the Two-Weapon Fighting Style can now make 3 attacks with their dominant hand and 2 attacks with their offhand.
I am not into the damage potential that comes with Two-Weapon Fighting, just the number of times you can make an attack. Hitting an opponent multiple times when it's your turn matters slightly more to me than seeing whether or not I exceed the damage potential of another Fighting Style.
As for the Duel-Wielding Expert feat, it hasn't changed much in A5e except that you can now swap out the offhand weapon with the Dual-Wielding property for a d8 weapon now.
