Welcome. The sly look works well for you
My vote would be to go for the DE Safety Razor.
I use a safety razor on the scalp (also use the ATX for a final pass to get any spots I may have missed). I've been using it on my head for about 2 years. Personally, I don't find it difficult to use ... at least now I don't. However, when first starting out I'd nick myself or use too much pressure and my skin would get irritated. After I refined the technique a bit, the shaves seem to be much better and closer.
Plus I like the experience better. I like using a brush and like trying a lot of pre-shave oil, shaving soaps, and creams that are out there.
