I'm looking at booking a tour of some markets outside the city of Bangkok. The second market depends on whether we go on Saturday or Friday. If we go on Saturday, we would go to Tha Ka Floating Market. If we go on Friday, we would go to Damnoen Saduak Floating Market. Our schedule is flexible so I'm wondering which of the Tha Ka or Damnoen Saduak market is better so we can choose which day to go on the tour. The first market is the Maeklong Railway Market, also known as Talad Rom Hub. 

Out of Tha Ka Floating Market and Damnoen Saduak Floating Market, which is better? Also, any info you have on either of these or the Maeklong Railway Market would be greatly appreciated. TIA!
