Although I do not have any data to backup or prove my assumption, that's my feeling; lower kW charging will be less damaging to the battery, over the long term, than higher kW charging. Pushing more current into the battery will cause a faster (greater?) rise in temperature, which is generally bad.
However, you can waste energy if you take it to the extreme: charging at Level 1 will mean that the car's baseline energy will be more of a percentage of the overall charge. A 72kW Supercharger seems to be a good balance (IMO). I don't have home charging since my electric rates ($0.325/kWh Tier1 and $0.406 Tier 2) are much more than a nearby ChargePoint CHAdeMO station ($0.19). The Tesla CHAdeMO adapter is limited to 50kW (ideal) which works out to about 42kW maximum in real use. If the CHAdeMO stations are tied up, or if I really need to save some time, I'll go to a local 72kW (Urban) Supercharger which is $0.24 off peak and $0.41 peak.
I have been CHAdeMO charging for the last 3 years. First year was covered mostly with L2 charging at work. When I retired, I switched over to CHAdeMO. My car has 26.4K miles and is a 2018 LR RWD. My normal 90% charge limit hovers between 268 and 270 miles; 100% extrapolated at just under 300 miles. It's about a 5% loss from my initial max range of 315.
