Is Kei Nishikori the best ever ATP player not to win a Grand Slam title?

If not, who is?

I think there's a handful of names who were better who didn't. Zverev would've been comfortably top of this list had he not had the season he's had

Tim Henman

Really... good all round game, especially in the net/volleying dept. If he had a destructive serve he most definitely would have won one.

Nah.. plenty of others who haven't. Don't think Tsonga ever won one but was in loads of semis/finals back in the day

Not for me. Ferrer, Rios, and Tsonga all better imo!

I’d say no. Think at their best Berdych and Ferrer were probably slightly better?

He is definitely up there, but I would probably go with someone like Marcelo Rios ahead of Nishikori as he was world number one .
