Betta solar skimmer vs Hayward wall skimmer

Good afternoon all, I'm considering getting either the Betta solar skimmer or installing a Hayward wall skimmer as an upgrade from last season's Intex floating skimmer. I felt like the intex worked pretty well but it was a bit of a hassle and obstruction with it being in the pool. We did use a solar cover at night as we have a rectangular pool with the wall mounted solar cover roller. So my question is, is it better to go with a wall mounted skimmer and continue to use the solar cover or forego the cover and let the robot run 24 hours a day? I did get the seagull SE last year as a cordless floor vacuum but did feel that it left some debris in the corners. Hence my wanting to remove the debris before it falls to the bottom. Thoughts?
