Depends on the nature of the campaign/adventure you play. I mean, do you always start at level 1 and get to level 20? I never do that nonsense. I usually stick to a band of levels like 5-10 or 7-12. Sometimes I just eschew leveling all together and you're the max level the adventure calls for during the entire campaign.

Leveling up in general can feel extremely tedious as you rearrange numbers and fill out new features, not to mention is sucks up table time. Definitely feels more 'worth it' if you get a radically game changing ability that has your character function entirely differently as opposed to +1 to X, Y, Z.
