Based on my experience, general auto store lithium complex grease is more than good enough in terms of water washout resistance, durability (not drying out) and lubricating performance.

As a retired heavy industry maintenance manager I have played with grease professionally and as a result used many products on many bikes over the years. Bike G is dead on in my dry climates experience, Southern AZ most of the year and Portland, OR and Bighorn Mountains only in the summer. Especially if one considers cost benefit and does practice reasonable preventative maintenance.
