Yes, I think so, exept for the lead.
It was shot at the same time as Fistful and released shortly after, so it couldn't be influenced by Leone.
All the SW ingredients are there, including the hero caught between american and mexican bandits.
And it was the first SW with a director not hiding behind an american sounding pseudonym.
Not a great, but a nice SW.
I would prefer this one to Jonny Oro, The Hellbenders and of course Corbucci's last 3 SWs. Not to mention his first.
