Pentel EnerGel RTX

I guess real downside is that if you look at the price on target like ten bucks for the five they're $ 2.00, a gel pen that is on the expensive side, ...

Downsides of rollerball pens is that they are gel and may smear more than ballpoints (but not all, like the pentel energel) and don't last as long as ballpoints. You also have fewer options when it comes to pen bodies. These are really good for journaling, because you can get very fine point pens (0.5mm or smaller). If you want something that will write for a really long time and has almost no smearing, stick to ballpoints (usually a Parker G2 style refill, which is different than a Pilot G2 refill).
