I only ever buy EDT/EDC/EDP, never aftershave.
My opinion on aftershave is
- no point in using it for scent when a more concentrated version exists.
- no point using it after shaving as it is too drying and harsh on my skin.
I generally prefer unscented balm eg Aramis Lab Series, but also use ADP Collezione Barbieri.
That of course is just my experience. If it is coming in a gift set (ie virtually free), I always seek out the aftershave balm over lotion / liquid. I suppose in that instance it is effective to layer balm and EDT, but only if it's free. In my experience, the gift sets in major retailers are a bit of a false economy, as one can usually find the EDT much cheaper on line.
