I am maried. My question is, is it better to file taxes as married filing seperately or is it better to file?

jointly. I made also $32,000 and my husband made almost same amount, we have three kids. Are we going to have some refunds if so, like how much? I pay baby sitting sometimes for the kids but don't have any receipt. Where is the best place to file taxes? is HR block better? Thanks in advance for your reply.
