You have to come to your own conclusions. Probaly less important on a brand new SSD, and one that has plenty of free space.
Mac OS X Lion has TRIM support for SSDs, HiDPI resolutions for improved pixel density? Latest in 10.7 Mac OS X 10.7 Lion is still available for purchase from Apple. While OS X Lion supports TRIM for all Apple SSD's, many third party SSD's are left without trim in OS X 10.7. Fortunately with a free tool called TRIM Enabler, TRIM support can be added to all SSD's running Mac OS X 10.7.2 and 10.6.8.

Once you make the choice stick with it; ie you do not want to be flipping back and forth as this will lead to data corruption.
Always advised to have a back up plan in place. How to create a boot clone
TRIM will release deleted blocks, It is recommended once enabled do a restart into SafeBoot Mode (hold the Shift key.)
Safe Mode does a Disk Repair and honors this trimforce command, effectively removing all the old deleted data.
The advantage of the TRIM command is that it enables the SSD’s GC (garbage collection) to skip the invalid data rather than moving it, thus saving time not rewriting the invalid data. This results in a reduction of the number of erase cycles on the flash memory and enables higher performance during writes. The SSD doesn’t need to immediately delete or garbage collect these locations it just marks them as no longer valid. This helps ensure that all storage cells are aged uniformly and maximum lifetime achieved.

All new SSD will perform well, it is over time when allocated blocks and pages become used, you start to see a loss of performance.
'TRIM doesn’t obviate the need for garbage collection—it works with garbage collection to more properly mark pages as stale. And you don’t need TRIM for garbage collection to work—but TRIM makes an SSD’s garbage collection more efficient.'

Apple just within the last couple OS X, supply the TRIM command in terminal for 3rd party SSD (eliminating the need for 3rd party methods to enable TRIM) this should tell you something about demand of this functionality.
