When comparing Carpalx QGMLWY vs Colemak Mod-DH, the Slant community recommends Colemak Mod-DH for most people. In the question“What are the best keyboard layouts for programming?” Colemak Mod-DH is ranked 3rd while Carpalx QGMLWY is ranked 15th. The most important reason people chose Colemak Mod-DH is:
Some people find moving D and H to the bottom row much more comfortable (especially with flat keyboards). Curved keyboards like the Kinesis Advantage also help with lateral motion. Regular Colemak on these keyboards might be the ideal solution since then you help resolve some of the cons of regular Colemak without adding on the ones from Mod DH.

Pros
Pro Easier to learn than QGMLWB
Keeps the ZXCV key in the same place as the very common QWERTY keyboard layout. More familiar than even than QGMLWB.
Pro The layout is basically good for most Latin languages
As vowels and consonants are mostly divided between 2 hands and most words in Latin languages are made of 2-letter (consonant+vowel) syllables, the layout keeps it efficiency not only in English, for which it was primarily created, but in other languages too.
Pro It takes much less effort to type than classical layout
The layout effectively combines not only changing hands methods, and rolling fingers as well, that makes typing a real pleasure.
Pro About the same score on the carplax test as the QGMLWB variant

Pro Much less lateral hand movement compared with regular Colemak
Some people find moving D and H to the bottom row much more comfortable (especially with flat keyboards). Curved keyboards like the Kinesis Advantage also help with lateral motion. Regular Colemak on these keyboards might be the ideal solution since then you help resolve some of the cons of regular Colemak without adding on the ones from Mod DH.
Pro Easy to learn from Colemak
No keys change fingers from Colemak (with the possible exception of Z , which is rarely used, in one variant).
Pro 'HE' easier to type compared with regular Colemak
Pro Letter G goes back to its original QWERTY position
This puts ING all on the middle row. Regular Colemak has G in the top row.
Cons
Con Very unpopular
Even rich on keyboard layouts variety Linux distros like Deepin, offering most of existing layouts, doesn't have this one. The situation on Android is not better, moreover if somebody get used to Swift-like keyboards, that do not have this layout, that person will be forced to have a second (e.g. qwerty) layout in mind.
Con Not always worth trying
The layout is great only if somebody uses it daily and a lot, like journalists, bloggers, writers do. In this case inconvenience to install the layout is worth use it. If you primarily use your phone/tablet to write some comments in Internet and other tiny writing tasks having such an unpopular layout on just your PC/laptop could be not justified.
Con Regular Colemak is more standard
Mac and Linux have regular Colemak keyboard options. This isn't an issue if your keyboard is programmable through QMK, VIA, etc.
Con H, M, V, B change from original QWERTY position
Regular Colemak has these in their original QWERTY position. The learning curve increases somewhat in Mod-DH.
Con Breaks up ZXCV slightly
Breaks up ZXCV (moves V over one space). Could cause copy paste confusion if also using other layouts like QWERTY. For ANSI layouts the Z is also moved to a new position.
Con No Innate Layout Configuration In Keybr
Keybr supports Standard Colemak but in order to adjust to DH Mod you must use an extension like tampermonkey and run a Script like this one and adjust to fit whichever variant.
Con Index fingers jump rows more often
Con More optimized for ISO and ortholinear style keyboards, not ANSI
