I don't have much of an opinion on him because I don't play the games with the Japanese vocal track turned on, but he's pretty alright from what little I've heard of his voice.
His English is very good though, which makes sense since he's an English teacher.
A few videos exist on youtube of the actors of Sonic and his pals singing. Here are a few videos.

I Love Junichi’s Sonic Voice He’s Calm And When He Speaks English it Sounds cute I Prefer Japanese Sonic

I like hearing people speaking English in other different languages.
Some of my favorites:
No reactioooon - Sonic and the Secret Rings
What!? - Sonic Lost World
Amy! Wait-wait-wait-wait! - Sonic Adventure

Jun'ichi Kanemaru, Sonic's Japanese voice actor since 1998, has responded to a reply I made on his tweet! It's a picture of his cat Glynn in a small box!
He has such kawaii pictures of his cat!
Jun'ichi-san, Sonic's first official modern VA, wished Sonikku a happy b-day on Twitter! (He made the tweet yesterday, as Japan is a day ahead of the US.)

Interesting thing I just found out:
Jun'ichi Kanemaru (Sonic's seiyu) and Kate Higgins (Tails' former VA) both do music, and they both have done jazz, and they both did covers of the same song (admittedly, it is a very popular jazz song BUT STILL IT'S HILARIOUS).
Here they both are:
Tails:

Sonikku:

Also, since Jun'ichi-san's Engrish is so difficult to understand, you'll probably need these to understand him better:
Also, yes, Jun'ichi-san uses his normal speaking voice for Sonic (the dude's like, gonna be 59 later this year), and Kate doesn't, so it doesn't sound like Tails singing like Jun'ichi-san sounds like Sonic singing, but still.
