Please clarify if you mean built or TAS, as they are quite distinct things.
TAS = played in the standard game interface (player presses keys and moves mouse) but with [some or all of] slow motion, segmentation, and extra info on-screen.
Built = created partly or fully via editing tic by tic, either manually or using a tool of some sort that enables tic-by-tic "programming" of the player's movements.
In the case of TAS demos, then pretty much all TAS demos before Andrey Budko added this feature would feature no illegal tics. After he did so, some players have avoided turning this feature on, but many have used it. (Sorry, I don't know off the top of my head which notable modern TAS players do or don't, but you could check with LMPC easily ehough, or just ask them.)
For built demos, unfortunately, illegal tics seem to have been pretty standard from the start, though some players have no doubt avoided them.
Coming back to your question, and assuming you mean TAS, then I'd suggest Cameron's pn22-123.lmp (HR map22 NM Pacifist, despite odd naming) for a nice short one, or Sedlo's 30nm1849, although it doesn't use the most modern routes, and MBF prevented him from using a few shortcust that were known at the time. Or his partial Plutonia TAS run. If you want something more Max style, then Cam's hf24-359.lmp (-complevel 3 or 5) is always a crowd pleaser. Actually, you could pretty much choose any TAS by Sedlic or Prosser without going too far wrong. :)
