Which cordless tube cutter is best for cutting copper pipes?

This week I was handling a minor plumbing repair at home after I spotted a slow leak beneath the sink and it escalated into a whole lot of trouble than I had expected. The old copper pipe was in a really difficult spot, so it’s kind of struggle using a regular manual cutter.After that, I thought about going for cordless tube cutters if things kept breaking around here as I really didn't want to keep struggling with very basic tools. I have checked the first local hardware stores and then I just continued surfing the internet on Alibaba and some other tool marketplaces to see lots of tube cutters in different models and sizes. Some of the ergonomic cordless cutters were actually quite good for small cramped spaces, Mainly for occasional home fixes instead of intensive commercial work. So here I am wondering what people here actually suggest for cutting copper pipes neatly without investing a lot in a device that is too big. If you do DIY repairs, which one you can tell that’s reliable?
