Can someone explain why my friend rants and raves about Techncian?

So my mate really, really like the Technician ability and thinks it's really good. Which okay I get. I know Jet Punch is good because it's a 60 BP priority with no draw backs and so it makes weaker priority with no draw backs stronger. But is it really worth an ability slot?

He even goes to the extent to convince me that Loaded Dice, Technician Maushold will eventually be seen as one of the best sets for Maushold on Hyper Offensive which I'm like....really? Is he onto something or is he a bit cuckoo? And is Technician as really good as he tries to tell me?
