Stainless is much more hard wearing than tin and tin does wear out  eventually, a bit like a conventional non-stick pan. 

Stainless Steel

The benefits of tin are that is better at heat distribution and tin is relatively non stick. Stainless steel doesnt colour unless it's overheated where as tin will  darken over time - it is almost like seasoning a pan as it becomes more non-stick as it gets older. 

Good Seasoned Dark Tin

If you use conventional nylon, wood or utensils specifically  designed for non stick pans with your tin pans they will last for a long  time. 

The major problem, apart from wear. with tin is that if it gets too hot it will  melt and bubble so it is not possible to dry fry. It is a good idea to have a good seasoned, cast iron skillet for very high temperature cooking.

New Tin Linings

If you want a set of pans that will look good and need less maintenance  then stainless steel is the better option.
