I had another go at learning Davinci Resolve this weekend and am now going to be using this forward. I was using Kdenlive before but since found out the latest version of the free version Davinci now supports GPU NVENC acceleration when encoding, which it didn't before, you had to pay for the full version for that previously. I was never able to suss out how to use GPU acceleration in Kdenlive as it is not officially supported. Davinci is not actually that bad for simple editing, it was just the number of icons and very busy looking interface that put me off compared to the simpler interface in Kden, but GPU acceleration makes it a no brainer now.
