Due to its Bipartisan Nature - a historic first - Final NJ Legislative map for the 2020 Redistricting cycle has had many changes that benefit both Democrats and Republicans on this map to varying degrees.
The Change that most clearly benefits one party, is the Alteration of LD-4 from Murphy +2.4 to Cittarrelli +5.4, a swing of nearly 8% towards the GOP in a competitive district.
Compared to LD-4 Most of the changes are modest, R Held LD-2 LD-39 & LD-40 as well as D Held LD-11 LD-36 & LD-38 get 1-2% Bluer
Whereas D Held LD-16, and R Held LD-8, LD- 21 and LD-25 Get a point redder.
Down from 24-16 Murphy, the Legislative district composition is now 22-18 Murphy. However, one of those gains (LD-21) was already R Held and the incumbents were likely to hold already, and the other one (LD-4) the NJ GOP's most Prime pickup for the NJ GOP, has D Over-performers.
On the net however it is unlikely that the NJ GOP gain either chamber this decade with LD-14, LD-16, and LD-36, being bulwarks against the GOP with a mix of strong D Trends(14, & 16) and strong Incumbents (14,36), the GOP is just locked out of power in the NG Leg.
