I'd say the Enterprise-E is more of a change than the Enterprise-A. At least with the E, it's a constant reminder that it's not the same ship.
The A looks exactly the same on the outside. The interior looks a bit different but it would've been updated in TFF anyway, with or without the suffix, because William Shatner wanted to update the look. And then Nick Meyer changed it again
. In TUC, it would be very easy to forget that it hasn't been the same ship all along.
The Enterprise-E doesn't look or feel like it's just some updated version of the D. It's not cut from the same cloth at all. To quote Worf, "It will not be the same. The Enterprise I
knew is gone."
