Just noticed you are in Sweden...would think Bosch would be your go to brand, they make great tools, as a carpenter, I love their power tools, my cordless drill and impact are Makita's and they are great, and have never let me down. Milwaukee's are very good also, but if hard to get there, then they're out. Your Swedish tools are probably very very good, I'd go with them if i were you!
18v have lots of torque, if replacement batteries are easy to get and affordable, 18v is the way to go.
Good Luck!
PS: Can't imagine finding Mopar parts there in Sweden, hard to even find decent OEM parts here in the US! Hats off to ya!
