I have 2.0 Furious Freds on my gravel bike, the extra volume is great. 2.4s would be pretty nice but I would not want an Ardent on gravel, that tread pattern would be brutally slow, I find them slow on singletrack. But if it works for you, thats all that matters.
You know I been feeling that too. I love the 2.4 size but the tread of the Ardent seems to really require more energy to move especially on hills or harsh winds. I just happened to have them around so I tried them for their size. I have some 2.2 Ikons hanging on the wall. Been tempted to try them again but just been hesitant because I hate to lose that extra .2 lol! New tires are not in the budget right now but I have been eyeing the Schwalbe Big one and similar tires.

By big I mean larger than what most gravel grinders consider big (38-42). I meant 2.2 and BIGGER whether that be standard,plus,or fat
