Personally I'd rather have a PHEV with ~50km EV-only range at freeway speeds, which would mean using EV-only for ~90% of my driving, while being able to use petrol for towing & longer trips, but (a) there are none available yet with a sensible price / performance mix (in Australia at least), and (b) the ATO has already indicated they will not continue to treat PHEVs favourably in the long-term.
