In the long run the best way to go if you have good useable cylinders. I’ve used both NOS or new cylinders they last about 5 years, first set of brass sleeves I put in are still going after nearly 20 years. I went with new cylinders on my latest truck as I didn’t have four sleeve-able cylinders left.

One note though there is an issue with using silicone brake fluid and sleeves. Silicone wants to leak between the sleeve and the cylinder some of the outfits over here will not warrantee the sleeves if you use silicone.

One other thing I’ve noticed keep the brakes adjusted so that the pistons stay out. This keeps the pistons and cups moving in the same area all the time. If you don’t adjust the brake shoes by the book you seem to end up with cups and pistons traveling in to far or out to far which seems to cause problems with cup wear and leakage.
