Enfamil neuropro vs gentle ease

My 5 week old has been taking Enfamil Neuro pro for about 4 weeks now. We have such a hard time getting him to sleep and especially getting him to stay asleep. He is fussy allll day, will only be content for about 10 mins. We make sure he is warm, clean and well fed and he just can’t be pleased. I literally cannot get anything done all day till my husband comes home. He is also very gassy because he farts all day as well, I thought it was normal because it meant he wasn’t keeping it in but my friend mentioned that it still maybe uncomfortable. Thinking about switching to gentle ease but scared about making things worse. Are they similar enough it wouldn’t be a problem? Also I read that it’s not as thick so spitting up may happen which out little guy already does. We have to burp often and keep him upright at lease 30 mins after and sometimes that doesn’t even work. Anybody switch to gentle ease? What was your experience?
