Guess worrying about "if we ever sell that it might be an issue for future owners." shouldn't really come into it at this stage... it's what you & your family would benefit most from... are you going to use the bath? or will it be mostly just showers?
If you have young kids, then bath is ideal for them for wash time, they might not take to the shower. If you are going for a bath with shower, then get a good quality sturdy bath. I've a shower over the bath in the main bathroom & the bath does feel "flimsy" when standing there and it's rarely used - prefer to use the dedicated shower in the ensuite.
