I think this decision can only be made on the basis of what you need.
What sort of motoring are you doing, and if you are considering fully electric , can you easily add a decent charge point at home?
personally my work van needs to be diesel as I don’t think there are electric alternatives, plus my van isn’t that old nor has it done many miles
my misses petrol car on the other hand rarely does more than 40 miles so electric could be a sensible alternative when we need to change it, which isn’t going to be anytime soon.
