Here is the best answer I am now prepared to give. I compared it against all of these that I also love.
-Thank you for inspiring the reason to use the Continuum again because I was even happier with it this time.
-The Continuum is entirely plastic underneath its metal exterior and honestly feels very fragile and easy to break. The user experience is very nice and knowing that mine is unused really gives me more comfort in using it. The experience is akin to using a TKmatic but for some reason it feels nicer, (dare I say) which could be its lighter feel in my hand. Using it just feels so effortless.
-The TX is probably my favorite because there’s something about the feel of the grip and the design of it that really just makes me happy to use and operate. Plus it’s all metal on the inside. I’m not one to definitively say that metal mechanisms are better but I will say that I have a higher sense of belief in their strength.
-The Turquoise TD is very nice but I am not comfortable with its grip.(I am shooting for the whole set but only because it’s such an awesome looking pencil.
-I wanted the holder to be my favorite but its grip is so narrow, I really like it and I enjoy using it but for want of a thicker grip, I’d have to rate this one as my least favorite of the 4.
