I guess the decision has been made by the OP, but I'll chime in anyway, mostly in defense of Resolve.
For TL;DR people:
I agree that Davinci Resolve is the editor of choice for higher end capabilities. The free version has massive power, and the one time paid version is far below the price of the Adobe Premiere subscription.
More to say:
On the other hand, I started with Vegas when it was originally built by Sonic Foundry, followed it to Sony and now on to Magix. I love Vegas (consumer and pro) and always recommend it to any seeking a lower cost editor. It seems far more intuitive than any of the others including the free open source offerings.
For many years I used HitFilm (free and pro) and found it worked well, but the lack of documentation finally drove me to Resolve. I still think HitFilm (especially the free version) is a viable alternative for basic editors. Just skip all the special effects talk. Similar to Resolve, you don't have to use all the power. They both work just fine for the basics. You don't have to learn all there is to know just to create relatively simple vids.
On the very basic front, iMovie and Windows Photo are the built in creators. (Before you all jump on me-NO, Windows Movie Maker is no longer supported/available. It has been depreciated in favor of Windows Photo. See
HERE) These both work, but most will outgrow them very quickly if you do more than one or two videos a year.
FWIW, Sage
