Picking up on your statement about being a beginner, I'd recommend the Get Wrecked itinerary as this would give you a greater variety of subject matter over Simply the Best, and allow you to get to grips with the basics of your rig.
Time of year does come in to it as in the summer months there is a good possibility of seeing large pelagics on Simply the Best, although this can not be guaranteed. On the whole, most of the dives would be wall dives, or hanging out in the blue hoping for something special. Those areas can also have quite strong currents, so it's hard to stay at particular point to get that "perfect" shot. Yes, there are a couple of wrecks, and the feeding stations, but their depth doesn't allow that much time on them.
Depending on the company you use, the Get Wrecked itinerary should include, apart from the wrecks, some of the Ras Mohammed reefs like Shark & Yolanda, Jack Fish Alley and Anemone City, all of which are quite stunning. You'd almost certainly do the Barge at Gubal Island which, for a photographer, is absolutely fantastic. Only 10 metres deep, but abundant with all forms of wild life and corals.
Other things to consider:
Photographing big stuff out in the blue, I think, is a much harder technique to master than wrecks and reefs. You'd get better results once you've got a handle on the basics.
"Get Wrecked" would include night dives most nights, whereas "Simply the Best" would probably have none.
There's much more distance to cover with "Simply the Best" which can be a pain, especially in rough conditions.
There are very few day boats in the North at the moment, so the dive sites can be relatively empty. Thistlegorm and Shark & Yolanda, for example, have been like diver soup in the past. I was out there last April, and we had all the sites to ourselves, all the time.
