I've already reviewed the two pen displays. Here's a comparison table based on my reviews.
|XP-Pen Artist 24 Pro||Huion Kamvas Pro 24|
|Price||US $899||US $899|
|Display||23.8-inch, 1440P. Even though it's not a laminated display, it does look very similar to Huion's.||23.8-inch, 1440P, laminated display|
|Colour support||100% sRGB, 83% AdobeRGB measured||99% sRGB, 81% AdobeRGB measured|
|Brightness||298 nits maximum brightness measured is significantly brighter compared to Huion. The higher brightness allows colours to appear more vibrant.||158 nits maximum brightness measured is sufficient but it would be nice if brightness could be higher.|
|Drawing surface||Matte screen protector||Matte glass can't be scratched|
|Shortcut buttons||20 shortcut buttons and 2 control dials. Changing settings is faster and easier with the control dials||20 shortcut buttons and 2 touch stripes|
|Video ports||USB-C, HDMI||HDMI, DisplayPort, VGA|
|Connection ports on the display||USB-C connection lets you use the display as a USB hub with two USB-A ports||Only video input ports are on the display|
|Pen||Supports tilt and 8192 levels of pressure sensitivity. Two pens included with protective pen case.||Supports tilt and 8192 levels of pressure sensitivity. One pen and stand included|
|Stand||Removable stand is stable||Removable stand is stable except there can be wobble at lowest position when display is resting only on the stand|
|VESA mount||10 x 10cm||10 x 10cm and 7.5 x 7.5cm|
|Drawing performance||Lines taper well. Line transition from thin to thick is smooth. Pen is able to maintain consistent pressure. Drawing performance is consistent and predictable||Lines taper well.

|Tilt sensitivity||Line breaks when direction changes from bottom to top, vice versa. Tilt doesn't work one inch away from the edge.||Tilt works well. Tilt working near the edge is hit and miss.|
|Glitches||The issue with tilt. Medibang Paint Pro (Mac) has line jitter issue||No glitches experienced|
|Driver||Has extra Fine Detail mode, Brush-Eraser mode||Display Switch works fine with Mac but on Windows there are three modes. On Windows activating Display Switch changes pen into mouse mode, pen mode on the other display, and back to own display.|
|Warranty||18 months||1 year, with option to purchase additional warranty (6 months for US $80, 1 year for $150)|
|Cables included||HDMI, USB-C||HDMI, VGA, USB-A|
The main significant difference between the two pen displays would be the matte screen protector on the XP-Pen vs the matte glass used by Huion. Matte screen protector can be scratched but matte glass can't. Screen protector can be replaced in the future when XP-Pen starts selling replacement screen protectors but who knows when that will be.
Both matte surface offer very similar tactile drawing experience.
Even though XP-Pen's display is not laminated, it looks very similar to Huion's laminated display. There's still a tiny gap between the cursor and the pen tip, which is probably not noticeable unless you're looking out for it. Both displays have minimal parallax or cursor-pen tip offset.
XP-Pen has the advantage when it comes to ports. XP-Pen supports USB-C in addition to HDMI. USB-C is versatile and also allows you to use the display as a USB hub. Huion uses HDMI, VGA and DisplayPort. VGA isn't that useful since computers from recent years no longer use VGA. And VGA can't support 1440P resolution.
