CI is best for shopping cart ?

Hi Team,

My company is interested to make own shopping cart framework based on CI , so my question is that Is Ci best for making shopping cart framework or not ? or CI 2.3.3 is best ?
Basically company has 10 shopping websites developed with core php but now wants to move in CI but not sure is this suitable for us or not ?
We found one library (gocart) which is stable i think but still not sure this will give benefit or not  .
Experts please give us a reasonable answer to start work on this.  

Thanking in advanced.
