Surging Sparks is the set rippers chase, almost entirely because of one card. Here's the honest read.
The chase cards
Pikachu ex (special illustration rare) is the headline — one of the most expensive modern chase cards, and it single-handedly lifts the set's expected value to open. Latias ex and the Alolan SIRs back it up.
Rip or hold?
Because one card carries the value, Surging Sparks is more of a ripper's box than a sealed hold — you're buying lottery tickets on the Pikachu. Most boxes return solid mid hits without it. Don't buy expecting the chase; buy for the rip.
Verdict
Worth it if you want the highest single-card ceiling per box to rip. If you want a specific card, buy the single — cheaper than chasing it. Compare prices to retail with the resale calculator and catch it at MSRP with QuickCatch. See how it stacks up in 151 vs Surging Sparks vs Prismatic.
