If you have decided to move on, why think so much and keep asking for other people opinion? Only you yourself will know exactly what you want, you are indecisive because you are not sure whether you should stay on in your current company.

Even if it turns out as a wrong career choice after you switch to the new company, you can always switch field later. There is no such thing as 100% perfect career choice. If you think that you can't fit into the culture or environment, then no need to think further about other new jobs/companies, best to just keep to your current environment. Be brave, if you want change.
