Imo, stay with complete 1:1 rips in an iso container.  An iso will play in most if not all popular players the difference being with or without menus and/or compatible with 3rd party software when/if desired.  Use Kodi as a front end and expand your horizons by following guide(s) now or in the future.  Skins are highly subjective and there are many.  Being a user for many years, I've found my combinations that work for me.  This particular skin fills most of my needs and desires.  Mike Silvo who maintains this skin is very open minded and completely on the ball imo. 

I agree.

However, in my case I'm forced to use MakeMKV as I use the Plex server and Kodi as the frontend with the plexkodiconnect add-on. Plex unfortunately doesn't support iso, folder structures such as VIDEO_TS or BDMV, etc. 

So once again it appears software simply isn't compatible with complete data and instead suggests, I mean force, the user butcher perfectly good data in order to satisfy its half ass functionality.  Bravo.
