Coders who have taken the time and effort to learn tableless coding understand when I say that coding without tables makes your life easier. It's quicker and easier to code a page without tables (once you're proficient) and it's much easier to change and update in the future.

All other benefits are secondary in my opinion. The search engine benefits are minor, but present and the page size benefits are also fairly minor. The benefits to my sanity as a coder is priceless.

I use tables for tabular data.
