Best place to go is like Simey says, the super-skyscrapers at the Al Sufouh end.
Ocean Heights, Marina Crown, Elite Residence are all accessible by turning off SZR, going through two sets of lights, doing one U-turn and then first right. No congestion ever. Also because they are right next to the tram stop you can take public transport without getting hot and bothered either. In the same area (but slightly more maneuvering required) are 23 Marina, Sulafa, Marina Pinnacle, Mag 214, Torch (don't do it), Princess, Marina Heights and the original Emaar 6.
All the other places on the marina require going through a myriad of one way systems, no-U-turn junctions, flyovers, underpasses and tram line deviations.
No issues on the west/south side of the Marina unless you want to drive somewhere else in the Marina.
Zumurud Tower, Orra Marina, Jannah Place, Opal Tower, Trident Waterfront all worth a look, and more or less have a dedicated exit to SZR if you're going to Ibn Battuta/Jebel Ali direction. Otherwise, you're on Interchange 5.5 in no time.
The area near and around the mosque is also easy to get to and from (at least from the Dubai direction). The second exit to Marina is barely ever congested compared to the first exit. Rents would be more reasonable too compared to the other end of Marina.
You might want to try the Bunyan and Sukoon towers as well, they're closer to the exit points and owned by the same individual landlord who offers several cheque options. Bunyan is quite close to the metro as well, as its actually beside it.
