Along with Kirsten, probably the pre-eminent openers in the era of the best pace bowling in history. Would venture to say this is fairly justified given that no regular Test opener averaged close to 50 during the 1990s.
On pure batting, Anwar was probably a better player of spin and had no long-term form lapses. As an overall contributor to their team, Taylor with his astute captaincy and flawlessness in the cordon places him fractionally ahead IMO. Anwar obviously better in ODIs, so this debate would probably be more fruitful if we stuck to Tests.
