If you do not run benchmark , there is 100% really no differences in daily usage speed even between a SATA II and SATA III SSD to the visual eyes. Maybe you can only "see" the differences when you do large data files transfer between SSDs.
Just buy the one that meet your budget and be happy.
Just sharing my experiences with you guys....
