I don't think it is better. I would almost always prefer DJGPP. I meant "if you must use HX, stick to OpenWatcom".

In theory, having only one binary that runs on two (incompatible) OSes would be nice (even if relying on external API emulation).

In 2008, Japheth recompiled the FTE text editor with HX. There he implied a "true flat memory model" was better somehow. (For DJGPP, I think for stability they restricted access to low DOS memory.) He also (rightly) said DJGPP was a bit bloated, having never been optimized for size, so his way gave a slimmer binary. (UPX helps but DJGPP UPX'd stuff runs much slower under NTVDM. Not sure whether specific DPMI hosts would be better overall with demand paging for speed or lower memory usage.)

HX also supports .DLLs. (DJGPP has DXE3, which has had a lot of work done, but I'm unsure if it's truly equal in robustness.)
