I think it is a gimmick but can't say for sure. The only thing I have seen that grafting makes sense for is soil born problems like nematodes, fusarium wilt or bacterial wilt. I have seen some dramatic increases in production with a few varieties but have also seen dramatic drops in production with some varieties that are grafted. Not all varieties work well with all root stocks so experiment with the varieties you really like with a couple of different root stocks and see which work out for you. As for TSWV my best advice is to plant some extra plants in the garden and have some seedlings ready in case you want to replace a plant that gets infected. I have tried quite a few of the TSWV resistant varieties and found most to be like supermarket tomatoes. The one exception that I found was Bella Rosa which is decent but not great tasting.
