If you want the fastest charging, Google will surely have an option (when their site is functional again), but I'd look at Anker. They tend to have some of the best and smallest (GAN) chargers, and for less money.
Personally, I plan on staying with my relatively "slow" 18w charger when I need a quick top-up, and 5w for overnight. No matter how well managed, higher charging = greater heat, and greater heat = faster battery degradation. Hoping to convince myself to stay with this phone for 3 years or so, and using the 33w charger regularly will result in substantially greater capacity loss over that time.
