I have both units. I won't comment on the accuracy as the specs are posted on both sites and I haven't independently verified them.
The Sper unit is a little more ergonomic but the probes it comes with are not useful, nor are any of the accessory probes from Sper Direct useful. It is not backlit as the photo suggests. I've been trying to return one and can't get them to respond to my emails.
With Thermoworks, you get a much better selection of probes that are suited for cooking and the service has been great. You might just give them a call.
