Yeah 2 schools of thought. Buy products where you can double duty the batteries or forget that and buy the one you like. EGO is REALLY good stuff. I had one of their trimmers. Really good. Gave it to my daughter and her SO for her house. Kicking myself for being so nice to that putz (not her, him). Anyway I wanted to try to keep one battery eco system. Which is why I bought the DeWalt. Now one would think how could that 20V DeWalt keep up with the Ego with much more powerful battery? Well, I have to say the DeWalt is amazing. Same with the blower. I bought the DeWalt blower to replace my gas one. Which was one of these

The DeWalt 20V is every bit as powerful and I don't come in smelling like an old engine, and I don't have to keep mixed gasoline around. And it weighs half as much.
In any case my decision to go with DeWalt seems to have been a sound one. I even had bought a DeWalt pole chain saw. Fantastic piece of equip. Punching far above it's weight. But, I sold it. I'm no lumber jack
After I had a couple limbs take unexpected falls (on to my head), told the wife. "I ain't doing this no more". Now, I pay a pro to do it, and sold the chain saw.
The only place I am gonna sway on my battery thing is this. Snow throwers. After listening to CR and buying that Toro POS, (another reason I have no faith in them), top rated but worst machine BY FAR I've ever used.
I will be looking for a battery electric snow blower/thrower. I picked up a little Snow Joe battery shovel/thrower this past winter. What a fantastic little machine. Sadly DeWalt does not make any snow equip. So I am looking at Snow Joe and EGO electrics.
I guess at that point then if I go electric lawnmower I could go with that battery ecosystem.
