which are not as efficient as gas versions, but offer essentially the same pros and cons.

Short answer:
We love it.

Longer answer:
Get the proper size. THWH's are sized by (temperature rise) per (gallons per minute). For example, let's say a model is rated at 30 deg temperature rise at 2 gallons per minute. If your incoming water temp is 70 deg, your low-flow showerhead (2 gal per minute) will give you a 100 deg shower. Quite comfortable...until someone starts washing dishes or doing a load of whites in the laundry. This might be fine. It works for us.

Also, to make the most of its efficiency, set its heat so that you shower using ONLY the hot water...no point in heating the water to an uncomfortably high heat only to cool it down again.
