Let's assume (hate that word) that both are equally sensitive with whatever coils you have.
The GT tends to give you a better ID on weak targets, but on the beach you will probably want to dig any and all non-ferrous targets anyway. So who would care about it.
Have heard that if you wire it right and the all metal switch is left in pinpoint on the GT, then it should work just like the Elite. Again, no difference.
You did not say if you intend to hunt in all metal and push the remote switch for disc to check targets, or if you want to default to disc for search and push the remote to pinpoint.
Most of us live with the extra knobs and switches that we seldom or never use. As long as you don't bump the control panel, there is no problem on either machine.
If you have some bad beach, you might want to hunt in all metal by default. I don't know if the GT remembers what the ground balance is supposed to be when switching back to disc then back to all metal search, or from switching back and forth between all metal search and pinpoint.
On the beach, you don't really need to do a precise pinpoint anyway. You will be digging with a big sand scoop.
