Either the DAS-II or the WISC-V would be good. I would not re-administer the WISC-IV to a (especially) gifted kid at one year re-test. The likelihood is way too high that there will be score inflation, which may very well obscure the second e. I do understand, though, that a gifted clinic might lean toward the -IV because of their clinical experience, and availability of the extended norms.
If we were talking about a younger 2e kiddo (like age 5 or 6), my preference would be the DAS-II, which I find to be more developmentally friendly to small people. Plus, it has the school-age form extension down to age 5, which allows for a much higher ceiling for 5-year-olds than the WPPSI-IV has.
For a 10 yo, though, either one would be fine, with a slight edge for the newer norms and more organized factor structure of the WISC-V.
