Like all guns, you must evaluate the gun as it currently exists. I think it counterproductive to worry about how the gun currently compares to how it might have been when OE. The better question is how it suits you as it is. Well made sleeved barrels are perfectly acceptable to me. Toby B. just did a really satisfactory one for me. Just like all other repairs/restorations, not all sleevings are equal. Shoddy work usually looks shoddy.
As for handling dynamics, handle enough guns where-in you pay careful attention and learn what you really like/need. Then "fugidaboud" the sleeving and decide if the gun meets your wants/needs.
