Doom95 ... I'd say there aren't any syncing problems about 95% of the time, since I've only had that happen once out of the few dozen demos I've been through.
Doom95 has excellent demo compatibility with Ultimate Doom's Doom.exe, but poor compatibility with Doom2.exe. A lot of Doom2.exe demos will desync if you try to play them with Doom95, and so will a fair proportion of Final Doom demos. The specific differences that lead to desyncs are different lost soul behaviour (in Doom2.exe) and a teleport bug in Final Doom.
If pushed to give a percentage for the number of Doom2.exe demos that desync with Doom95 I'd guess at 30%, though it will be higher for longer demos and lower for shorter ones.
OK, I've just tested 32 compet-n Maxes, one on each map of Doom2.wad: 11 desyncs. So my guesstimate may have been a bit conservative.
To watch vanilla demos reliably, use the original DOS exes themselves, Prboom(-plus), Eternity or Chocolate-Doom. BTW, I've recently tested all the Compet-n pwad and Final Doom demos with prboom-plus: just 1 desync out of about 3500 demos (plus 6 where you need to add in a special command-line parameter to get them to play back). The current test version has a new feature for the auto-loading of wads according to the file-name, which makes things even easier (the current default patterns suffice for many compet-n demos).
myk describes how to get hold of the DOS exes here. Though if your only interest in them is for watching demos, there are simpler solutions.
