Should I use “selbst” or “sogar”?

Question

I am trying to write a sentence similar to the following sentence in German:

Selbst/Sogar die besten Schwimmer ertrinken können.

In English, my sentence would be:

Even the best swimmers can drown.

Should I use "selbst" or sogar"?

Answer 1

There is no difference in what both variants express.
But the correct order of words is
Selbst/Sogar die besten Schwimmer können ertrinken.
