I believe the ''so much hype" came from the US Aviator - they are nice guys good in marketing, have huge costumers and speak English. But once they decided to change to Parajets...Tornado hype diminished rapidly.
I fly Nitro directly bought with a visit to the Polish factory at Rokitno (Rokitno 2, 05-870), I spent some time there and I saw those guys are serious about production, but marketing is another issue, especially when they sell mainly with a French company Air Conception...and it is not about English language marketing neither here in Poland nor in France.
Knowing the Nitro engine quality and reliability I would not hesitate to buy Tornado...just Nitro is good enough for my style of flying, including tandems from time to time
