Philly's in a better position to build through the draft, whereas Denver's in a better position to build an immediate contender. Depends exactly on how much you value the window of contention: Philly's plan is super risky, but if things generally break right, they'd probably have a significantly wider window of contention than Denver. The trade off, as I just mentioned, is that the plan is very risky and could fail, whereas Denver has the relatively safe option of cashing in on their assets right now and possibly contending for the next few seasons or so, depending on who'd be left after trading for an impact player or two.
I'd probably pick Denver. They have much more established talent at the moment.
