Timewreck all day. IMO Chernobyl is a great strain, but the flavor isn't my favorite and the JTR high can lean a bit to paranoid for me vs the Vortex side that is paranoia free and has an endless cieling that also doesn't allow much tolerance build up.
I'm super happy to have Sub's TW cut in my garden. If I had to choose the Golden Ticket or Sub's TW, TimeWreck wins every time.
