The general consensus is that indica-dominant strains are preferred for relaxing in the evenings, whereas sativa-dominant strains are more uplifting for the daytime.
Read up about the strains being offered by your suppliers, on a site like leafy.com, to see which of those two categories they fall into.
I was bitterly disappointed with the G Pen after I saw it ranked as the supposed "#1" by one or two of the popular review sites. Useless seems like an extreme term, but relative to other great ones on the market, it was close to that - after two tries, I gave up on it.
In that price range, a friend got the Boundless CF and was very happy with it.
