If I had to choose between these two, I would pick the Samsung Galaxy S21 FE 5G.

Here's why:

I value the convenience and the versatility of having wireless charging, which is something the Realme lacks. The camera performance is very important to me, and the fact that the Samsung has been tested and has proven itself to be a high-performance camera is very reassuring, especially when combined with the versatility of the lenses, which is very useful in all different scenarios. Finally, the screen is more durable, and as someone who is prone to dropping phones, I prefer that extra layer of protection. While the Realme has great performance for gamers and it has great features, for my current needs, the S21 FE is a better match.
