I had a similar discussion while shooting on Sunday. Having recently got an FFP scope, I can say, at lower magnifications the reticle is getting so small it becomes, for me, unusable. As most (all) of my shooting does not involve changing magnification between shots (indeed 3 out of 5 of my scopes are fixed magnification), there is no disadvantage of me using a SFP. So, why did I buy a FFP? Because I liked the glass and the reticle featured a centre dot, and my eyes centre circles far more intuitively than cross-hairs.

But all to their own when it comes to scope preferences.
