Couldn't pick one, but I love these:
dunlop 200g
dunlop revelation series
Prince Tour series
Head Prestige(s)
hyper carbon pro staff
Yonex Regna series (all models)
Donnay formula and pro one racquets
Prince Japan Models
The day-glo orange donnay that Agassi used (who knows what racquet that was under the boss colour scheme).
