My ryobi 18V is lighter and better balanced than my corded one.
I did upgrade when I needed to replace my exceedingly old batteries to the longer run time ones.
For me it was a great addition to my arsenal of anti-weed tools.
Is it a corded or battery operated?
While my corded is far more powerful than my battery one I love the battery one for tight spaces and yes even going into the big flower beds.
Practice on a scrap piece of wood. Start with the pressure at 80 and if they are not sinking go up a bit. Sunk to deep? Turn the air pressure down a smidge. I find it takes a bit of practice with a new air stapler to find the best pressure for THAT gun.
It will also vary a bit if the wood is...
