Comparing White Pens

I just can't seem to find a reliable white pen to save my life! I ordered Stampin' Up Chalk Markers which is suppose to look like chalk but it isn't and it does not smudge (none do)....I think they have it for that 'chalkboard' look that is popular. I compared it to the other white pens I have. (I used one clear one because I love how it 'hints' something is there and figured it would be great for details on dark paper as well.) I threw the Marvy Pen out, I couldn't even get it to write its own name.

Note: I wrote normal fast writing for each of these. I didn't even sit down to write, all were written the same.

The Stampin Up Marker shows up good and is not really blotchy (note the Glaze white pen which writes good for the first letter but the more letters I wrote I got more 'glaze' then 'pen" I got.)
Results: The White Glaze pen is out!

All the pens seem to leave a heavy mark where I first put it down and where I pick it up however the Stampin' Up marker is better about it than the Gelly Roll pen. With that being said, the Gelly Roll pen is thinner and those heavy marks can 'add' character to a font. It all depends on the look you want.
Results: Both Stampin' Up Chalk Marker and Gelly Roll pen are good depending on the look you want.

I also want to add that although I am not impressed with the Glaze White Pen, I am loving the clear one on cardstock that isn't shiny. Be warned when using it, if you are not at the correct angle you can't see what you're writing which is why I wrote the "G" over but I see many possibilities where this pen will be useful on dark cardstock.
Results: Clear Glaze pen is great to add 'not in your face' details.

As for the Crayola Crayon. I used that as sort of a 'base' for this comparison since most people are familiar with what it looks like.
Results: Used as 'base-line'. I don't use for journaling but a 'must have' in my supplies for other uses.

What is your favorite go-to pen for writing on dark cardstock? Mine is the Stampin' UP Chalk Marker.
