I use VUM to do that. It would show you those patches that are applicable and those that are no longer applicable and the order in which they show up in the list is important. Newer patches have newer dates.
The real question is not which supercedes but is the fix in one (SG) in the other (BG). One is a BugFix (BG) and the other a Security Fix (SG). For that you may need the changelog if it is available from VMware.
First go to VMware ESXi 5.5, Patch ESXi550-201403102-SG: Updates ESXi 5.5 tools-light vib (2065827) | VMware KB then to VMware ESXi 5.5, Patch ESXi550-201512403-BG: Updates tools-light (2135793) | VMware KB.
The information you need is in there. Specifically look at tools-light version numbers.
