I’ve been using double edge safety razors for a long time since other methods were never comfortable. I also liked to experiment with different hardware and soaps until I found my preference. I would recommend against using a razor with a design that has multiple stacked blades.

The additional blades often cause additional irritation because the first blade removes the shaving cream, so additional blades are scraping the skin without sufficient lubrication. If you are prone to ingrown hairs, these are also likely to make that much worse.

If you want a closer shave, I recommend doing multiple passes (with the grain, then across, then against; skip the against the grain pass in sensitive areas or entirely) and reapply shaving cream between passes.

Lastly, I prefer having a fixed head razor (no pivot) because then I can control the angle. This allows you to adjust to the cutting angle of the blade and to adjust the aggressiveness of the cut in different areas. A pivoting head takes away this control.

If you need recommendations, for gear let me know. I’m happy to share my knowledge.
