you mean you prefer the looks of the Vapor..
When i shoot a marker, i prefer the overall feel and balance with hopper and bottle. The only way is to try them first before having your own personal opinion, others may find it different.
The Vapor has only recently been released and is made by a new company. From what i have read, there is'nt many dealers in the states that will stock these, and im not sure if any dealers in the UK have these as yet.
Unless you have a dedicated dealer here in the UK, you may find it hard to get parts if any problems.
