Hi At least as I understand it:
Properly done with TRIM, the file system lets the disk know each time a file is deleted and space is now empty. With garbage collection, the never used sectors are accumulated together to make erase and re-write faster. To some extent they are complementary operations. You pretty much need both of them. TRIM so the disk knows what's not being used and GC so everything stays tidy.
