If you are considering between Blackberry and Android device, this means most of the benefits of blackberry OS is not relevant to you.
Get a 1+one.
However, I would NOT rush myself into buying a phone just because it's on sale for couple of hour once a week or so. (Unless it was Blackberry Passport or Classic at %50 off, then I would...)
I had both, I missed the qwerty so I am on passport now. However, I do miss the gestures and camera of the OPO. They are very similar phones but I would get another OPO over z30. The OPO held it's value way more than the z30 did as well. Maybe wait for the next generation phones unless it's cost prohibitive to do so.
Either way, good luck.
ps. Do not get the OPO cover, quality is subpar

Reason: spelling
Considering that you already have a Blackberry, I'd go with the 1+1 if I were you. Besides, there's "supposed" to be a newer all touch blackberry coming this year.
Your choice. One plus one is a the best Android phone because of the price range. If you are interested in that be sure that it will get android lollipop or not otherwise it is good enough to consider it.
