Depends on your card/bank and point value. 1-1 is probably the lowest value you'll see. Pretty much every portal provides better "value" on points if you book through them for travel, either your airfare, hotel, car rental, or all three, IF you can plan ahead well enough in advance and have some general flexibility in when you can fly, where you can stay, etc.
Depending on your offers, APR, etc. you could be "better off" opening a new card and just getting a direct 5% cash back or even more points to use if you do have that flexibility.
But if you don't want to deal with their travel portal or can't plan ahead, might as well get something if it works for you.
