18 gauge finish nailer recs

I have a metabo 18 gauge finish nailer that isn’t performing how I’d like it to it is not that old maybe 2 years. I tried my buddies who has a rigid 18 gauge finish nailer and it shot with some real power like a piston it felt smooth and sharp seeing rigid I assumed it would be worse. It ended up being way better. I tried my grandpa‘s old senior 18 gauge finish nailer that I gave to my brother and once again that fired 100 times better than my metabo. I’m over the metabo I bought the best one they had it’s a POS. Any recommendations ?? Corded / pneumatic nailers only!!! Im shooting through hemlock doing a T&G ceiling
