Depends on the situation. Very few times I do onchain txs nowadays, when I do is mostly for opening/closing LN channels. All my regular bitcoin spending is only on LN, not onchain anymore.

If I open channels and I am not in a hurry, I put 2sat/vbyte and wait. If is just a normal opening channel, I check on mempool and set the medium fee. If I am in a hurry, I will let the app decide the best.
