I grew over 200 varieties of tomatoes for a trial some years ago. Of those, the tastiest and most resilient were chosen for growing on in subsequent years. The results from those further trials were mixed, depending on how the season progressed. All were grown in tunnels, given no artificial heat beyond that needed to raise them. It proved that mostly it was not what you grow, but how you grow it. Or more to the point, how they coped with the weather. To an extent, anyway — the right variety does help. If you can remove the vagaries of the weather, of course, then so much the better, which is why such good quality tomatoes are in our shops, grown under glass where their environment is precisely controlled.
I've also compared grafted plants with their un-grafted counterparts. Grafting does not guarantee a crop, it protects only against soil-borne diseases — there is no protection against blight, for instance, which is the usual reason British tomatoes' prospects come to a rapid halt. If soil-borne diseases are present, then there is an advantage, but if the soil remains healthy there is no measurable difference. This is not me poo-pooing grafted tomatoes, absolutely not, but I do want to emphasise that grafting is an insurance policy, not an investment.
