I asked this question on social media and ordered a few of the pen’s suggested to me. I’m on a mission to find a smooth writing, non-blobbing, easy to hold (for a long time) pen. I have a gorgeous Fisher Space Bullet which I adore for its look, and the satisfaction of putting it away, but the grooves press into my finger and feel a bit uncomfortable. I very much appreciate the depth of colour a black Sharpie gives but can’t bear its bleed through a page. Also, it’s not a fast writing pen. I tried a Uni-Ball Eye after previously being recommended it but found it too scratchy. I was told to try the micro because that is “flowy” which sounded good. The Pilot G2 gel ink rollerball got the most enthusiastic mentions so I ordered one of those. People also suggested the Papermate Flexi-Grip and the Stabilo Pointball.
I ordered from Cult Pens and firstly, how cute is this? It arrived with a little pack of love hearts!

Here are my initial feelings.

My top two are the Papermate and the Stabilo. It seems I prefer to write with a biro although I prefer the look of the gel pens on the page. If anyone has any other recommendations let me know. No ink pens though! They may be fancy but they get a big no from me.
