Davinci starts to make a huge difference when you want to edit 4k+ resolution files natively. Especially ProRES and Davinci RAW.I have both Davinci Resolve (Free) and Wondershare Filmora X (Purchased). For Davinci to use the GPU you really need the studio version and I'm not ready to plunk down the $300. With the new version of Filmora I found it is using the GPU more frequently and while I don't have a beast of a GPU the editing and playback is much smoother than Davinci without creating proxy files.
While I think Davinci is the way to go for pro editing and growing your abilities Filmora is an inexpensive beginner editor and has multiple payment options depending on what you want including lifetime upgrades for ~$99 (1/3 cost of Davinci)
I still have Davinci installed as it does do some things better (Time lapse photos) but I now use Filmora for most of my actual video editing.
I'll note one thing. Much of editing efficiency is in the keyboard commands and shortcuts. I've had to edit across multiple NLEs over the years and it usually takes my fingers a few hours to "remember" I'm in a different NLE.
