Each successive game engine includes interface improvements and playability features. Off the top of my head:
* Right-clicking on any tile shows its contents, not just its coordinates (introduced in TCB). Some objects and monsters will also give further useful information, e.g. a snake will tell you how long it is.
* Left-clicking on bombs shows their explosion radius (introduced in TCB). This will come in useful in JtRH... oh, shall we say
quite often?
* Opened green and blue doors remain visible (introduced in TCB).
* Tar transparency is available in-game without installing a mod (introduced in GatEB).
Against that, you lose each game's unique title screen music and, in my opinion, something of the authenticity of the atmosphere. (I don't know whether playing JtRH in a later engine will actually use the new room styles -- I think it does?) For me, that authenticity is more important, so I played all the way through JtRH in its own engine, and I'm doing the same with TCB.
