AU Zenith Plus offers a good joining and renewal bonuses that compensate for the card fee charged. However, the accelerated rewards rate of 2% on select spending categories with a base rate of 1% is low for a premium card, especially when compared with other cards like Cashback SBI that comes at a much lower fee and offers 5% value-back on all online and 1% on offline spends. If we compare the value-back rate on travel expenses, travel cards like Axis Atlas and Air India SBI Signature still outshine Zenith+ by offering up to 5% and 4% savings respectively. So, the one advantage that Zenith+ seems to have when it comes to its rewards program is the rewards redemption ratio of 1:1 which is quite good and can give this card a slight edge over other all-rounder cards with a high earning rate but a low redemption value.
