As much as I love retractable clicker pens so I don't have to worry about losing the cap, the Signo UM-151 in 0.5 is the smoothest, most reliable, and most visually pleasing ink and body amongst all the pens I've used (Zebra Sarasa 0.3, Hi Tec C 0.4, Signo 207 0.5 & 0.38, Jetstream 0.7 & 0.5, Uni Style Fit 0.38).
This blue is bright (unlike Sarasa's blue which is oddly closer to navy or blue-black) without looking silly. I look forward to using this pen for many years to come and just continuing with refills.

I like the larger size barrel compared to the Hi-Tec-C and Slicci pens. The rubber grip is nice, and it runs a clean line. I found that the ink is waterproof as advertised.

I've been using this pen for the past few days after a recent shipment, and I have to say it writes like a dream.

I personally haven't had an smudging issues. It's everything I've been looking for: a decent grip, .5 mm line and smooth ink flow.

I just wish they sold them in the US.

Although the Signo DX 0.5mm pen writes more smoothly than the 0.38mm version, the 0.5mm Signo DX has certain issues with giving out too much ink when writing. Smudging is a real possibility when writing with this pen.
