As a fellow southpaw, I was convinced to buy a bunch of their recommended pens (IIRC their standalone "best pens for lefties" article is more thorough than the left section in the "best pens of $current_year" article).
The Pentel EnerGel (specifically, the "Pentel EnerGel Alloy Gel Pen - 0.7 mm - Black Ink - Silver Body") is the best pen I've ever used. It feels magically smooth with minimal smudging. For me it writes much better than the Jetstream, although if you do a ton of writing you might prefer the grip on those. I also really like the multiball (for writing on non-paper surfaces), the power tank (aka the poor man's space pen) and the Sarasa dry gel pens (less smooth than the Energel but the designs are fun)
