Vertex - avoid the Apex, OS use is exactly the use not recommended for JMicron drives. Even though you get fast reads, you get stuttering when doing things like web browsing and other common tasks because of all the background saves that occur. The Vertex will be far better for your needs.
If you're on a budget, consider the Corsair S128. It has slower read/write speeds, but as has been discussed on this forum many a time, access times and IOPS are what make SSDs fast, not sequential read/write speeds, and so because they have cache, the Corsair S128 (and other first generation drives using the Samsung controller) will both far outperform regular HDDs and give you better overall performance than the Apex.
