SLE-spec does not offer much more than the SL, apart from the 4.2-inch color display in the instrument cluster and an auto-dimming rearview mirror. However, unlike the base model, it does allow you to add many of the desirable features available across the range. This means that you can have it with AWD if you need the extra traction, or you could spec on the missing safety features like blind-spot monitoring and rear cross-traffic alert. Alternatively, you could go the comfort route with power-adjustable seats and dual-zone climate control, but upgrading to the SLT makes more sense.
