1.6 for a product site?

[alfredopacino]

Hi, I'm about to start another ecommerce, the last one is stucked on 1.6.0.6 and I can't upgrade because I tried to upgrade and the category menu doesn't work anymore (the issue in 2 words: the menu is shown completely exploded and the implode button doesn't work).

(obiouvsly that's not the only thread I exposed this issue, just the first I found)

 

So I'm wondering if you suggest me to use 1.6 or 1.5 for a stable product site.
