...or might simply find that utilising such a table just isn't worth the effort in their particular piece of software.
Use them if it's going to make a worthwhile difference to your particular piece of software. Seems reasonable enough.
As for the poor soul who opened this pandora's box of a thread, I can't see look-up tables making a vastly huge impact. It will depend on what you are doing with these four sprites. And backgrounds. And whatever else. Yes, it may be that using look-up tables gives you a gajillionty-hundredty frames per second, rather than only a billionty-twillionty. Of course, the end-user's monitor may only display 100 of them.
So there isn't a yes-or-no answer, really. All you can do is suck it 'n' see.
