Ultimate SEO URLs or Simple SEO URL ?

What is the better choice and advantages of one over the other?

I'm using both for my shops.
Some might say it's not worth it, but I think if you know how to properly implement the url rewrites, they can help.
Simple seo is harder to install but has more features in the backend. They are both nice add-ons but you need to know what youre doing before jumping in that boat as they could mess up your ranking in the search engines.

You don't need any of these "SEO modules". The search engines prefer it if you retain the dynamic link. There is no material advantage to using them - they are based on deprecated and archaic concepts - and if anything, they can actually be detrimental to efficient SE spidering and indexing.
