<p>When slicing with Slic3r Prusa edition the top layer of most models turns out pretty bad. There are usually small gaps or weird patterns. This does not happen with Ultimaker Cura, it will have a nice smooth top layer. Is there anything settings wise that I can do in Slic3r to get the same quality of top layer as Ultimaker Cura?</p>

Yes
, you can show more than 300 lines in the terminal; just
disable auto scrolling
(
reference
).
Disabling Autoscroll now completely disables cutting off the lines (so
  you can have way more than 300 lines while that's disabled), filtering
  has been improved too and doesn't cause scrolling anymore.
Note that with disabled autoscrolling, you will be able to see more lines up to the point that the buffer is full. If you need even more lines to monitor, just enable the logging the data to file
```
serial.log
```
. If you open the options page (OctoPrint Settings), just tick the box for "Log communication to
```
serial.log
```
" under "Serial logging" of the "Serial connection" options.
This serial logging file is typically used for debug purposes, but as can be read from the options, it comes with a warning:
While this can negatively impact performance, a
```
serial.log
```
can be
  incredibly useful for debugging any issues observed in the
  communication between OctoPrint and your printer.
You can either access the log file through the OctoPrint options/setting through the "Logging" options tab, or direct download/copy from the logging directory:
on Linux: ~/.octoprint/logs
on Windows: %APPDATA%\OctoPrint\logs
on MacOSX: ~/Library/Application Support/OctoPrint/logs
