Both the GNS-430 and GNS-480 have GPS/ILS/VOR/Com all in the same box.
Would not be different in that regard for either of them. 480
apparently currentyl has WAAS capability and this is supposed to be an
upgrade for the 430. There are many other differences between them
but they both have the same basic capabilities. The only current
difference in approaches you could fly would be ones requiring WAAS.

I think the difference between having vertical guidance for GNS-480 =
approaches,
and not having it with GNS-430 approaches is a HUGE difference.
It's even bigger than ILS approaches versus Localizer-only approaches.

The 430 cannot get that capability without being recertified under =
TSO-C146a,
and the 430 hardware would need to be replaced to achieve that =
performance level.
I can't imagine Garmin upgrading the 430 now that they own the 480 =
design.
