Subjectively worse, we don't have enough battery powered cars to compare the timelines with gasoline powered. They contribute to more waste, regardless. Battery packs need replacing 5 - 10 years, are not easily recycled or disposed of and their manufacture and mining of materials still isn't a net positive in terms of pollution. There isn't a one size fits all solution. Going all electric trades one issue for another, cleaner air for more polluted rivers, cities around mines and factories and battery disposal and recycle sites. I personally have no problem with electric but I dislike hearing people tout it as the solution to all our vehicle woes. It isn't.
