Got my Steam Co vape package the other day.  Went for both reserves: Gentleman's and Old English Orchard.  I dripped both in a fresh KP long-barrel on arrival: outstanding.  I'm pretty picky about vapes but these both get a thumbs up.  I haven't tried CLR, so I don't know how Gentleman's compares, but it does remind me of the sort of complexity of 5pawns Gambit and Grandmaster with a more robust flavor profile and a stronger TH than 5pawns line.  
Surprisingly, I find Old English Orchard to be the winner of the two reserve flavors from Steam Co, though it does have almost a week on the DOB of my Gentleman's.  I will add my thoughts on the two reserves after I try it in some fresh clearo's and a couple KFL+ builds over the next couple weeks.  
Edit: As to leakage, there doesn't appear to be anything wrong with the bottles, but I did notice moisture on my hand after dripping the KP atomizer and noticed a slight sheen on one of the bottles.  It was clearly the e-liquid as it had the unmistakable aroma, though both bottles seemed topped off.  It was the GR bottle.  Pressure/heat forced a tiny bit of the liquid out of the cap and it was soaked up by the labeling of the bottle?  I dunno that it's right to call it a leak, but it seems consistent with 2 drops of e-liquid running down the bottle over a period of a couple days.  Perhaps it's a remnant of the filling or capping that isn't immediately noticeable?  The bottles don't have any leaks.
