I actually like his new voice. xDD Jim Miller actually explained why Sombra's voice is different in Season 9. It is because it is Sombra's true natural voice while the voice in Season 3 is a ghostly, ethereal voice. This means he was not fully formed back in Season 3. Plus, they got Alvin Sanders to voice Sombra because Jim Miller said he didn't reprise his role due to wanting a more professional and well-experienced voice actor for the role. I would have loved to hear Jim Miller's Sombra again, but what can you do. LOL So that made me appreciate the new voice more. LOL I loved Season 9's premiere personally! It is so great and I love Sombra in it as well! He finally made his grand and epic return! ^^
