That really depends on how you use your Mac. I put one in a 2010 MBP and it certainly boots faster; but I only reboot it sporadically so it really wasn't that much of a game changer. Beyond that, in my day to day use (Word, Excel, web browsing, email) I really didn't notice much difference. Parallels appeared to be quicker, especially when opening a VM.
The down side was far less storage space as I went from 500GB HD to 256GB SSD. I had to be careful how many photos or videos I left on the Mac.
I suggest looking at how much disk space you use and see if 256GB will be enough, otherwise any speed improvement will be offset by the need to constantly clear disk space.
Overall, I was happy with going to an SSD but it didn't represent a huge boost in performance.
