The Optimas (Red Top especially) have much lower internal resistance (= more starting current) than liquid electrolyte batteries of the same size, they will suffer more deep discharges and they have lower natural (internal) leakage rates than other types but.... if they are left discharged for long they will be ruined too. Any lead-acid accumulator (which these are) has to be kept at a very high state of charge to have a long life. It's actually quite amazing how long a life they can have.
So, I'd say, if you are sure that your vehicles' electrics are not draining them while they are resting (or, it seems, as long as your name is not Jack), the Optimas will serve you well - but so should standard batteries. If they are not being drained, it's high temperatures (above about80°F in old money) that will cause them to discharge naturally and lose the will to live, not our winters, or autumns, or springs, or most summers.
