Do front derailleurs inherently kinda suck?

But: It seems to work much more smoothly on the rear than on the

one (Deore vs. LX)?
Yes.
Shifting the rear is far more frequent (and thus subject to wear) than
the front, so the rear derailleur is typically of higher grade
componentry.
Is it because the front derailleur is a bit out of alignment?
Yes.
Front shifts are jerkier than rear, but shifting shouldn't miss or cause
prolongued chain rub. It seems that your front mechanism needs adjusting.
Or is it just that front shifts are inherently more awkward than
rear ones?
Yes.
The front has the task of making 10- to 12-tooth gear changes to a chain
loaded with up to 800 pounds of tension. The rear has to make 1- to
3-tooth changes on the slack part of the chain. What do you think?
