That sounds probably right. He could be a bit higher or maybe lower. Let's see who is probably ahead of Agassi--Tilden, H L Doherty, Gonzalez, Rosewall, Laver, Sampras, Borg, Kramer, Nadal, Perry, Budge, Vines, Lendl, Connors, McEnroe, Hoad. Some may be somewhat arguable and some are no brainers ahead of Agassi.
Here's some that are also possibilities to be ahead of Agassi-Trabert, Djokovic (I think he's already better than Agassi at his peak but for the career, not yet), Sedgman (also probably better than Agassi at his peak and arguably for career), Emerson, Segura (I think he may be better overall if you take into account the strength of the Old Pro Tour ), Newcombe, Gimeno (was a great player but played on the Old Pro Tour), Ashe. Some of these players may be below Agassi in some ways but you can argue they were superior at top level.
For example Arthur Ashe won according to Vainqueurs 71 tournaments in his career. He probably won more. Ashe won the first US Open, Wimbledon and the Australian plus he was the 1975 WCT Championship which essentially was a major at that time. At his best Ashe was incredible with his huge flat first serve and his great wide swinging slice serve with power off both sides. Push come to shove I would pick Agassi as the overall better player but Ashe on a medium to fast court, if he was playing well in my opinion would be favored over Agassi.
