So true that it is all about buying some time... Every plant goes down with some funk or other at the end of the season.
Resistance can make a huge difference in a commercial greenhouse. We had a row one summer of plants that were very susceptible to ?? don't even know what it was. They went down more than a month before the others, although they did produce some fruit.
Sick tomato plant mess is pretty gross...
I'm always steering toward resistance and away from the dreaded high maintenance varieties.
