If you mean the tithi style options in a Jain Panchang/calendar, then the difference is usually this:

• All Samuday Tithi = shows a combined/general view for multiple Jain samudays or traditions, so it is meant for wider community use. Jain calendar apps describe this kind of support as covering multiple communities/samudays in one system. ( globalcal.in)
• Ramsuri MS Tithi = shows the tithi according to a specific Jain samuday/lineage style, connected with the Ramchandra Suri tradition. In Jain calendrical practice, different samudays can follow different tithi decisions, which is why separate tithi styles exist. ( en.wikipedia-on-ipfs.org)

In simple words:

• All Samuday = broader, common display
• Ramsuri MS = one particular tradition’s tithi rule

So if your temple or upashray follows a specific samuday, you should select that samuday’s tithi style; if you want a general view, use All Samuday. ( globalcal.in)
