This discussion is pointless, and some of the arguments being made border on silly. You are not going to convince me to open this hand with a one bid, and I am not going to convince you to open it with a two bid in second seat. So let's leave it at that.
I don't think preemptig is wrong with this hand, not my personal choice, but it is close.
But for me a 6-4 is closer to a 7-3 than to a 6-3. I normally adjust 6-4s between 2 and 3 level for suit qualities, ODR and vulnerabilities; this hand has decent suit qualities and big ODR due to honnors on long suits. So if preempting I would always do it at the 3 level unless unfavourable, 2♠ looks like heavy underbid at favourable to me.
