I'd bid 6♠. I don't know what agreements you have with your partner, but mine state that after a preempt we strive to bid what we think we can make expecting one trick from partner. If partner has the A♦, we have 3. Even without that card, if we get a club lead and partner has hearts, we can set up that suit for discards. I'm not worried about spades, partner has them, but opposite a stiff I'm not sure they will run the suit with no loser. If your agreements in this case include a solid suit, then I'd bid 6♣ looking for 7.
The flip side, and this depends upon your understandings with your partner, is that partner may have stretched because you were behind. If you think partner is likely to stretch here, then 5♠ is the bid hoping partner will bid 6 with a true hand.
Edit add: After thinking about this, I asked myself what would 5n be here? Would you play it as GSF, or pick a slam? If pick a slam, this hand might be perfect for that.
