I like the hotshot over the greddy yes. The greddy is nice looking but only replaces the stock cast manifold leaving the first cat. Also HS header has a nice long runner try-y (4 into 2 into 1) setup, and the greddy is still restrictive do to size constraints. I have also read that the greddy likes to crack.
There is supposidly a second gen greddy I heard about, but I know nothing about it or any release date. I liked this oner and got it and really didnt research anything after that
This is a temp mod anyway, as soon as I got FI Ill get this header to fit on my gf's 92
