So, once the spending embargo has been lifted, which one should I consider?
To be fair, I've only used the Instant Pot (and can't recommend it highly enough!!). Perhaps something to consider is the availability of spare parts (sealing rings, valves, replacement inner pots, etc) and accessories, all of which are widely available for the Instant Pot, though I've heard that these are not so easy to come by for the PKP. I may be wrong there, so don't quote me - it was something a friend complained about a year or so ago and things may have changed.
On the other hand, of course, the PKP is a good deal cheaper to buy than the IP. Plus, because of its extreme popularity, the IP is frequently out of stock on Amazon
