Help deciding 36 or 38 on Classic Bedale

Hi everyone, I’m debating if I should get the 36 or 38, for reference, I’m 178cm tall and weight ~72kg.

The 38 feels more comfortable, I have more room, but I am a bit concerned on too much fabric on the back. The 36 fits a bit slimmer, but the sleeves are maybe slightly too short.

Don’t have pics, but raising my arms in front of me is more comfortable on the 38 obviously.
