If I want to find gold no matter how small, I'd grab the SDC.
If I want to find gold less often, but have a better weight after many trips, the I'd go 4500.
Mind you, the 4500 with the 14x9" Evo is very close to the SDC on small stuff, but the SDC will purr along happily on bad ground with no fuss.
With the 4500 you will need to learn to adjust it to suit various conditions, so a bit of a learning curve. I like the adjustability of the various audio settings on the GPX's, which
makes it run exactly as you want.
Best thing about the GPXs, is you can strap on a big coil and hunt to 1m depth. Can't do that with the SDC - it is a more specialised tool, but it does its job very well.
