Though for certain offers, they are superior and we go with them. Entertainment.com is one example where we would go with MyPoints over a Airline portal.
I also check evRewards which lists the payout for various other sites including MyPoints. That way I can compare everything myself. I also check TopCashBack which is strictly cash and often does better than points.
