I found that DC had too much of a 'clamping' force which gave me discomfort. Additionally, the older examples have brass plugs which get corroded and make noisy electrical contact - the newer ones are chrome. My Lightspeed Sierra is a good compromise for ANR at about half the cost of Bose. I've done around 700 hours with them now, still excellent. I've replaced the ear cups and mic cover once, but these are 'consumables'. Good battery life and Bluetooth connectivity, works well with my phone.
I see SEHT are marketing a really inexpensive ANR, might be worth a look. They've been really helpful to me keeping our Club headsets going, but I haven't tried their ANR.
ANR is always going to be the better option, if the headset is designed from the ground up for it. The reason is that the headset can be made so much lighter and less fatiguing to wear - see my comment about DC above.
