I think they are all called Easy Smart. Are you looking at the 108PE versus 108E? If you are, the PE version has POE (power over ethernet) ports which you probably don't need unless you have cameras you can power via POE.
I'm guessing that Easy Smart Technology is probably fancy talk for Power Management (where unused ports are shut down) and maybe QoS for data prioritisation but I'm probably wrong
Just had a quick look, I think it just gives extra configurability such as port mirroring which you won't need.
The Easy-Smart switches are kinda layer 2.5! I've a faulty one hanging around that can still be used for port mirroring. If you don't need the switch interface for Vlans then the cheaper unmanaged layer 2 switches will do - and they can sometimes be faster too!
