Well, everyone's situation is different but the new earn rates do suit my spending pattern immensely as the vast majority of spend on the card comes from restaurants, travel and overseas shopping trips (so apart from rip off Australian pricing that's now another reason to get my Prada shoes overseas). In fact, I can't think of any better card now. I cancelled the Charge card due to the insurance downgrade but the Reserve has been great on the new earn rates - ended up getting a comp Gold charge card anyway which is what I'll use for hotel pre-authorisations (only other thing the Platinum Charge card was truly useful for).
I've never put ATO charges through the card as I've always ended up getting refunds rather than owe taxes. That might soon change as we now own an investment property which should make us liable for taxes in the next tax return... But right now, the Points I'm getting has actually proportionally increased on the whole vs the old 1.5 Points/$ rate.
1 weird thing I noticed - I'm getting the 'restaurant' rate with bars I visit (mainly coughtail bars). It's a hit and miss but probs about 3 out of 4 bars have posted as 'restaurants.' Some of them do serve tapas but none are what you'd consider actual restaurants. I guess it would depend on whether they're defined as 'restaurants' in AMEX's back end. I could see this information when I used the Charge card but the credit card doesn't seem to provide this level of visibility.
