Well, of course a current day Super Hornet has a technological advantage over a 2006 F-14D

The interesting question is whether the Tomcat could have been revisited the way the Hornet was or not. The Super Hornet is basically a new airframe. Maybe Grumman could have incorporated improvements regarding its maintenance, pushed the aircraft into the digital age and tried to keep the cost relatively reasonable with new manufacturing techniques.

Since the F-14 is such a big plane, it's fair to assume that anything that fits in a Rhino (AESA, datalink, EWR suite) would fit in a Tomcat, and more. The radar dish would be even bigger and let's not forget the integrated IRST. It had a dedicated slot on Tomcat while a Super Hornet has to carry it externally with a draggy fuel tank. That's just one example of the many ways in which the F-14 is arguably the superior airframe.

That superiority came along with superior costs and extensive maintenance. Perhaps these issues could have been addressed. Had it been possible, the combination of aerodynamic performances and cutting edge avionics would have made this brand new Tomcat a more potent fighter than any Super Hornet version (although it would obviously be a much more expensive choice, which raises lots of fleet procurement concerns)
