The answer is it depends on the routes you travel and what type of ticket you buy. In my case, under the previous FF rules I would earn approximately 22,000 redeemable miles for my typical west coast-Europe round trip. Under the new changes, I peg at the maximum 75,000 redeemable miles per round trip. Even with devaluation I make out quite a bit better.
In terms of benefits, the best are free same day change and free changes and cancellations for your mileage tickets (which basically means every award ticket is fully refundable). I also don’t have problems using my systemwide or regional upgrades and I like the flexibility next year where GPUs and RPUs are interchangeable.
So for me the answer is: yes
