Lets suppose you are a big rig shaper aiming for R&D lock with click compression, because that is the type of deck you would play Upya in.
Sure Gamble is a popular economic card, in that it provides a profit of 4 credits with a credit requirement most runners have or can comfortably click to. It provides its credits in a burst, providing you with more credits immediately.
Upya is essentially a run economy card, (save for the rare combo turn usage), that is only usable with click compression, (such as Magnum Opus or Professional Contacts).
If you run every 2 turns to compensate for multi-access runs, economic limits, and corp securing of R&D, you will gain 3 power counters in 6 turns. That means you gain 1 click every 2 turns, and with click compression making every click worth ~2 credits, amounts to about ~1 credit every turn, which is... actually an okay power level. In 6 turns it will even with Hedge Fund.
However, for this card to provide that benefit, you would need to have a click compression card and your breaker suite already installed, in addition to its memory requirement. You may also have difficulty in running on R&D.
Another comparison would be to Data Folding, which needs 2 free MU but does occupy them, and evens with Sure Gamble after 7 turns.
