This is not even debatable. 
I didnt say he is the best, but he's in the conversation.
Dude has never dropped a wack album, and has one of the most soulful voices in R&B.
His first album with "Sweet Lady" and "Lately", "Nobody Else" Platinum.
The second album with "I Like Them Girls", "Baby Boy", "Make Up Your Mind" "What Am I Gonna Do. Gold.
The third album "I Wanna Go There" and "Signs of Love Making", "All Ghetto". Of course "How You Gonna..." but the rest of the album cuts(title track, "I Must Be Crazy", "Kinna Right") were my favs. That album and those songs changed music for me.
Fourth album, "Alter Ego", a 2CD album, was a true R&B album at a time when R&B was beginning to change. The first disc R&B, 2nd disc was Tyrese rapping. This is his best album overall....production/writing from Tricky, R. Kelly, Underdogs, B. Cox. No skippable tracks on this one.
One of the GOAT bedroom jams
Fifth album, "Open Invitation". My least favorite album of the bunch, but I really need to give it another listen b/c it was a successful album.
"Stay" was a huge single for him, "Nothing On You" was successful too.
TGT 
Just simply a GOAT R&B album for me. My fav R&B album of the past 10 years. Tank shined the most b/c he's obvious a producer/writer on many of the tracks, but Tyrese completes that album with his soulful voice.
Finally his last album, "Black Rose"
"Shame" is one the best R&B songs in I don't know how long. A true soulful ballad that stayed near the top of the charts for MONTHS. "Dumb Sh*t", one of the most creative/honest songs about a dude cheating....a great song held back by the title. "Addict", another classic bedroom jam.
In addition to all this, dude is one of the few singers who sounds exactly like his records.
in this performance, maybe even better than the record
another one
If you look at his entire body of work, he's been one of the best and most consistent, while still being somewhat underrated, in my opinion.
